How to Buy a Bus: 10 Things to Consider Before You Buy
A bus specialist's checklist for your first or next bus, from sizing it to the trip you actually take most often to the one question nobody thinks to ask about air conditioning.

Buying a bus comes down to ten decisions, and Carpenter Bus Sales can walk your committee through every one of them. Size it to the trip you take most often, confirm who can legally drive it, then work through air conditioning, storage, new or used, warranty and delivery. Get the first decision right and the rest follow easily.
Key takeaways
- Size the bus to the trip you take most often, and ask your drivers what size bus they feel comfortable driving, says Rick Cassels, Regional Sales Manager.
- Ask whether a bus A/C has a single compressor or dual compressors.
- Every used bus Carpenter Bus sells is inspected and reconditioned before delivery.
- Carpenter Bus includes a warranty with every new bus and van:
- PlatinumCare: 8 years, unlimited miles, free for churches, ministries and senior care communities.
- SilverCare: 5 years or 60,000 miles, free for every other new buyer.
- GoldCare: 7 years or 70,000 miles, an $800 upgrade.

What are the 10 things to consider when buying a bus?
Ten decisions shape a bus purchase, and Carpenter Bus walks buyers through them in roughly this order. The first four do most of the work, because they set the size, the driver and the comfort of the bus. Work down the list with your committee and the rest falls into place quickly.
- Purpose. Who rides, how often, and how far.
- Capacity. How many seats you need on a normal week, driver included.
- Driver licensing. Who on your team can legally drive the bus you are buying.
- Air conditioning. Whether the cooling is built for your climate.
- Storage. Where luggage, instruments, wheelchairs and gear actually go.
- Accessibility. Whether a wheelchair lift is something you need now, may want later, or will not need at all.
- New or used. What each one costs you up front and later.
- Running costs. Insurance, fuel, maintenance, registration and storage.
- Warranty and service. Who fixes it, where, and for how long.
- Timing and setup. Graphics, lettering and getting the bus to your lot.
How many passengers does your bus need to carry?
Size the bus to the trip you take most often, not the once-a-year big one. Rick Cassels, Regional Sales Manager at Carpenter Bus, tells buyers to start with the trip that happens week after week. If that trip is 12 people, a 15 passenger bus is usually the right answer, and you can solve the rare large trip another way.
That last part is worth sitting with, because buying for the big trip is the most expensive habit a committee can fall into. A bus built for 40 people still costs you for 40 seats on the Wednesday night run with nine riders.
Going bigger changes more than the sticker price. Federal rules point to a CDL (a commercial driver's license) once a vehicle is designed to carry 16 or more people including the driver. Some states set stricter rules than that, and our guide to CDL requirements by state covers where your state draws the line. Crossing that threshold usually narrows your volunteer list down to the few people on it who are able to drive your bus. The bus itself is longer and taller, which means more parking space, a bigger turning radius and, in a lot of cases, nowhere on the property to keep it out of the weather. Insurance carriers rate on capacity and how the vehicle is used, so the size you choose shows up in the premium you are quoted. Ask your carrier what the bus you are considering would cost to insure before you commit to it. Fuel and maintenance follow the same direction.
Set against that, the once-a-year trip has easier answers. Run two smaller buses and bring two drivers. Rent a larger bus for the weekend you need it. Or take the trip in two groups. Carpenter Bus rents buses to organizations in Tennessee and Texas, and your representative can tell you whether renting for that one weekend makes more sense than owning a bus that sits for fifty-one others.
None of that means the large bus is wrong. If you genuinely fill 35 seats most weeks and you have CDL drivers, buy the large bus. The point is to match the bus to your normal week, then plan around the exception.
Two more checks before you settle on a number. The first one is your drivers. "Ask your drivers what they're comfortable with," Cassels says. "They may not be comfortable with a 25-passenger bus." A 40 passenger bus that nobody on your volunteer list will drive is the wrong bus, no matter how well it fits on paper.
Second, ask the people who ride. Cassels suggests talking to your seniors and your regular riders about what matters to them, because buy-in from several groups usually produces a better decision than a spec sheet does.
Carpenter Bus always counts the driver in a passenger number. A bus sold as a 15 passenger bus means 14 riders plus the person behind the wheel, so check that any figure you are comparing counts the same way.
Carpenter Bus delivery records show that roughly two-thirds of the units Carpenter Bus delivered since January 2022 (records through July 2026) were small buses, meaning 15 passengers or fewer. That describes what Carpenter Bus customers chose rather than the national market, but it shows that a small bus is clearly the most popular choice.
| Group you move most often | Bus class | Driver licensing | Where to read more | Browse what is available |
|---|---|---|---|---|
| Up to 15 people, driver included | Small bus | No commercial license in most states | 15 passenger bus guide | Small buses for sale |
| 16 to 30 people | Medium bus | Commercial license required in most states | 25 passenger bus guide | Medium buses for sale |
| 31 people or more | Large bus | Commercial license required in most states | 35 passenger bus guide | Large buses for sale |
What bus brands and models does Carpenter Bus carry?
Carpenter Bus carries seven manufacturer lines for new vehicles: Starcraft, Glaval and Collins on the bus side, and Forest River Vans, FR Conversions, ADA Boy and LA West on the van side. Between them you can get anything from an 8 passenger executive van to a 46 passenger bus, which is why the labels on dealer websites matter less than the specs underneath.
A church bus, a shuttle bus and a senior care bus are often the same vehicle with different seating, so do not get stuck on the label. Here is what each line we carry is actually known for.
| Line | Known for | Capacity |
|---|---|---|
| Starcraft | Small and medium buses on Ford and Chevy chassis, with floor plans for everything from frequent routes to occasional group trips. Models include the Starlite, Allstar and MVP. | 15 to 46 passengers |
| Glaval | A full line from 21 to 40 feet, with Steel Safe construction built for heavy-duty commercial service. Models include the Universal, Legacy and Concorde II. | 14 to 45 passengers |
| Collins | Compact buses including the Magellan, built for high safety standards and easy handling on residential and city streets. This is the line our activity buses come from. | 10 to 34 passengers |
| Forest River Vans | Low-profile passenger vans on Ford Transit and Ram ProMaster platforms, for organizations that want to stay non-CDL. | Up to 15 passengers, driver included |
| FR Conversions | Wheelchair accessible van conversions with extra interior height and width, built for paratransit and specialized fleets. | Up to 14 passengers, or several mobility positions |
| ADA Boy | ADA-compliant van conversions on Ford Transit and Ram ProMaster platforms, with custom floor plans and short lead times. | Up to 15 passengers, including wheelchair positions |
| LA West | Executive and luxury conversions on Mercedes-Benz Sprinter, Ford Transit and Ram ProMaster platforms, for a first-class passenger experience. | 8 to 15 passengers |
Used inventory is broader, since it can include other makes on Ford, Chevrolet, GMC and Freightliner chassis. Availability changes constantly, so check current inventory or ask your representative what is on the lot before you settle on a model.
You do not need to arrive knowing which line you want. Tell your Carpenter Bus representative how many riders you carry on a normal week, who will drive, whether anyone uses a wheelchair or a walker, how far you travel and what you haul, and whether the vehicle has to be an activity bus.
That last one is worth explaining, since it is the one category that is a legal distinction rather than a configuration. An activity bus, or MFSAB (multifunction school activity bus), is built to the same federal structural safety standards as a yellow school bus. It does not carry stop arms, flashing red lights or yellow paint, and private organizations can buy it. Private schools, daycares and camps often need one because some states require it for licensed childcare transport. It is not a yellow school bus and cannot be used as one for home-to-school routes, so check your state rules before you order. Carpenter Bus does not sell yellow school buses.
Those answers narrow seven manufacturer lines down to the two or three buses worth looking at, and that is the part we do for you.
Does the size of the bus change who can drive it?
Yes, and this is the decision most first-time buyers underestimate. Federal rules point to a commercial driver's license (a CDL) when a vehicle has a gross vehicle weight rating of 26,001 pounds or more, is designed to carry 16 or more people including the driver, or hauls hazardous materials requiring placards. State rules sit on top of that.
The word that matters is designed. Licensing follows what the bus is built to carry, not how many people climb aboard. Pulling two seats out of a 20 passenger bus does not move it under the line by itself.
Some states, including California and Connecticut, apply stricter rules to churches and nonprofits. Seat count alone never makes a particular driver or vehicle exempt, so confirm your situation with your state licensing agency or call a Carpenter Bus representative at (800) 370-6180 before you assign drivers.
If your driver list is short, that is a real argument for staying at 15 passengers or fewer. If your group has outgrown that, start recruiting licensed drivers while you shop, not after the bus arrives.
Already own a bus your drivers cannot legally drive? Carpenter Bus handles CDL to non-CDL reclassification in-house at Franklin, Tennessee and Elm Mott, Texas. The manufacturer issues updated capacity labels and our team installs them before the bus leaves, which typically takes about two weeks once your letter and photos are in. This is more involved than pulling seats out, and not every bus qualifies, since it depends on the manufacturer, the age and the condition. Send us the bus and we will tell you whether yours is eligible.
What should you ask about air conditioning before you buy a bus?
Ask one question: is this bus a single compressor or a dual compressor unit? Rick Cassels, Regional Sales Manager at Carpenter Bus, puts it plainly. "The single most important question you can ask is, is this unit a single compressor or a dual compressor bus?" BTU ratings alone, he says, can be misleading.
BTU, or British thermal unit, is the measure of cooling capacity. Cassels says 45,000 BTU is the common setup on smaller shuttle buses. In his experience that is not enough for places like the Southwest and south and southeast Texas, even on a 15 passenger bus. Carpenter Bus orders 60,000 to 70,000 BTU at a minimum there. On the Gulf Coast, in Louisiana and Mississippi, Carpenter Bus has started ordering significantly more, always with dual compressors.
Here is why it matters more than it sounds. A bus that cannot keep up in August makes riders miserable, and riders who are miserable stop riding. Cassels puts the consequence simply: when your people get mad, your ridership dies, and that defeats the whole reason you bought the bus.
Tell your representative where the bus will live and how hot it gets there. That one detail changes which units on the lot are right for you.
How big is a bus, and will it fit where you park it?
Most commercial shuttle buses are about 8 feet wide and 9 to 10 feet tall. Length is what changes with capacity, running from roughly 23 feet on a 15 passenger bus to 40 feet on the largest shuttle buses. Width barely moves, which is why a bigger bus is usually a parking problem rather than a driving one.
| Bus | Typical length | Typical exterior width | Typical height |
|---|---|---|---|
| 15 passenger | 23 to 25 feet | About 96 inches (8 feet) | 9 to 10 feet |
| 20 to 25 passenger | About 25 feet | About 96 inches (8 feet) | 9 to 10 feet |
| 30 passenger | 28 to 32 feet | About 96 inches (8 feet) | 10 feet and up |
| 35 passenger and up | 32 to 40 feet | About 96 inches (8 feet) | 10 feet and up |
Figures come from the Carpenter Bus size guides for each class. Inside the cabin you have roughly 93 inches of width to work with, which is what sets the seating layout. Exact measurements change by manufacturer, model year and configuration, so confirm them for the specific bus you are considering.
Before you fall in love with a floor plan, measure three things at your own property: the gate or driveway you will come through, the turning space in your lot, and the height of any covered entrance or garage door. A bus that fits your group but not your parking lot creates a problem every single week.
What does a bus cost to own after you buy it?
The purchase price is the start. Plan for insurance, fuel, routine maintenance, registration, storage and driver training on top of it. Henry Headden, President and Owner of Carpenter Bus, says a well-maintained commercial bus typically lasts 10 to 15 years, or 150,000 to 250,000 miles, and that regular preventive maintenance is the biggest factor in which end of that range a bus reaches.
| Ongoing cost | What drives it | Who to ask |
|---|---|---|
| Insurance | Passenger capacity, how the bus is used, driver records, your state | Your insurance carrier |
| Fuel | Engine, weight, how many miles you run each month | Your Carpenter Bus representative |
| Routine maintenance | Mileage, duty cycle, how closely you follow the service schedule | The Carpenter Bus service department |
| Registration and inspections | Weight class and your state's rules | Your state agency |
| Storage | Whether the bus sits inside or outside | Your own property |
| Driver training and licensing | Whether the bus requires a commercial license | Your state licensing agency |
Routine maintenance is the line most committees underestimate, and it is also the one we can put real numbers behind. Our breakdown of annual bus maintenance costs prices a year of routine service at the Carpenter Bus shop for two example buses, covering oil changes, safety inspection, filters, tire rotations and brakes. The short version: a 15 passenger gas bus costs noticeably less to maintain each year than a 38 passenger diesel, and the gap is wide enough to matter when you are choosing between sizes. Fuel filters, bigger tires and bigger brakes are where the money goes on the larger bus.
Build your budget around a written maintenance plan rather than around repairs. Walk around the bus before and after every trip, keep a dated service log, and use the fluids and parts the manufacturer specifies. Federal rules also require emergency exit inspections at least every 90 days and a periodic inspection at least every 12 months on covered vehicles, and your state may require more.
Storage is worth a sentence of its own. A bus kept under cover holds its appearance and its condition better than one that sits in the weather for ten years, and that shows up again when you trade it in.
If you finance the bus, the monthly payment sits on top of everything in that table, so work it out before you commit rather than after. Carpenter Bus offers bus financing and leasing options on new and used buses, and terms change, so confirm current programs with your representative.
Should you buy a new bus or a used one?
A new bus gives you the longest service life, your choice of floor plan and full Carpenter Bus warranty coverage. A used bus costs less up front and carries whatever factory coverage is left. Carpenter Bus sells both, and which one is right depends on how long you plan to keep the bus and how much of your budget is going into it up front.
The honest tradeoff is predictability. New means you know the history because there isn't one. Used means you are buying someone else's maintenance habits, which is why the inspection below matters so much. Every used bus Carpenter Bus sells is inspected and reconditioned before delivery, so you are not starting from a blank page on condition.
What should you check on a used bus?
Start with the floor and the roof, together. Randy Sadler, Service Manager at Carpenter Bus, who oversees the Carpenter Bus service shop in Franklin, Tennessee, says floor replacement on a used bus can run roughly $2,000 to $8,000 depending on the damage and the scope of the repair. In the buses his team sees, failed or weak roof seams are a usual source of the water intrusion behind that damage.
Work through this list on any used bus:
- Soft spots in the floor, especially along the walls and under the rear seats.
- Roof seams and any sign of past water getting in.
- Service records, and whether the previous owner kept to a schedule.
- Mileage in context. Highway miles on a shuttle are easier duty than stop-and-go routes.
- How the air conditioning performs after the bus has been running for a while, not in the first two minutes.
- A real test drive, at highway speed, with someone from your team who will actually drive it.
*Repair figures above are estimated shop ranges, not quotes. The real number depends on what an inspection finds.
Carpenter Bus does not put a Carpenter Bus warranty on used buses. An optional service contract is available for purchase on qualifying used buses. It covers powertrain, meaning the internal lubricated parts of the engine, transmission and drive axle rather than the whole vehicle, for 12 months or 12,000 miles with a $100 deductible per visit, at a current price of $1,050. Ask your representative whether a specific bus qualifies and exactly what the contract covers.
*Service contract pricing and eligibility are current as of publication and can change. Confirm today's terms with your Carpenter Bus representative.
What are the key features to look for in a church bus?
Safety, storage and accessibility, in that order, decide how happy you are with a church bus three years in. Carpenter Bus configures buses for churches every week, and these are the features that come up on nearly every call. The same three lead the list on a corporate or hotel shuttle, where fast loading and luggage space carry more weight.
How much storage do you really need?
More than you think. Rick Cassels says inadequate storage is the regret he hears most often from Carpenter Bus customers after a purchase. Luggage, sound equipment, sports gear and wheelchairs all compete for the same space, and storage is nearly impossible to add later.
You have real choices here: overhead racks, a partial-width rear storage area, a full-width rear compartment, or a rear luggage wall that trades seats for space. Our guide to storage options on buses walks through each one.
When do you need a wheelchair lift?
Sooner than most committees expect. If you carry senior adults, plan for accessibility now rather than trading the bus in five years early. Most Carpenter Bus buses can be configured with a rear or side wheelchair lift, and commercial lifts from Braun and Ricon handle up to 800 pounds. Each wheelchair position takes the space of regular seats, so build that into your capacity math.
Which safety features should be on your list?
Ask about seat belts on every seat, a backup camera, grab rails at the entry, non-slip flooring and high-back seating for longer trips. On a church bus carrying children and older adults, the entry step height and the grab rails matter more day to day than almost anything else on the spec sheet.
Can you customize a bus that is already on the lot?
Often, yes. Carpenter Bus can add quite a bit to a bus you like before it ever reaches you, and when something is not already on the vehicle, the sales team works with the Carpenter Bus service department to see what can be done. It is a bus-by-bus conversation, so tell your representative what you want and let them tell you what is possible on that specific unit.
Options buyers ask about most often:
- Logos and lettering, partial graphics, or a full vehicle wrap.
- Seating layout and upholstery.
- Flooring.
- Storage configurations, including overhead and rear options.
- Wheelchair lifts and securement positions.
- Technology and comfort items such as cameras and audio.
A new bus ordered from the factory gives you the widest choice, since the layout is built to your spec from the start. A bus already in stock gets you on the road sooner. Bring your list to your representative early, because some choices are easy to add and others decide which bus you should be looking at in the first place.
Engine is one of the choices made at the bus, not after it. Carpenter Bus sells both gas and diesel buses, and most of what we sell is gas. Diesel becomes available as you move into heavier chassis. Our guide to gas vs diesel bus engines covers which one fits your mileage and duty cycle.
How does the warranty work on a new bus?
Every new bus and van from Carpenter Bus includes warranty coverage, and all three levels cover the entire vehicle bumper to bumper. What changes between them is who qualifies, what it costs, how long it lasts and the mileage limit. Coverage ends at whichever limit you reach first.
| Program | Who gets it | Price | Length | What it covers |
|---|---|---|---|---|
| PlatinumCare | Churches, ministries and senior care communities | Free | 8 years, unlimited miles | Entire vehicle, bumper to bumper |
| SilverCare | Every new bus and van buyer | Free | 5 years or 60,000 miles | Entire vehicle, bumper to bumper |
| GoldCare | Any new bus buyer who upgrades | $800 one time | 7 years or 70,000 miles | Entire vehicle, bumper to bumper |
Carpenter Bus offers the only 8-year unlimited mile warranty in the industry for churches, ministries, and senior care communities. If your organization is not in that group, you still receive SilverCare at no charge and can upgrade to GoldCare.
Claims are simpler than most buyers expect. Contact the Carpenter Bus warranty department before any work begins, take the bus to a qualified local shop of your choice, pay the $100 deductible, and Carpenter Bus pays the approved shop directly for approved parts and labor. You do not have to bring the bus back to us to use your warranty, which means a bus bought from Carpenter Bus can be serviced close to home wherever your organization is. Routine maintenance and consumable items such as wiper blades, filters and fluids are not covered, and Carpenter Bus extended warranties are not transferable if you sell the bus. An underlying manufacturer chassis warranty may transfer under that manufacturer's own terms.
How long does it take to get a bus?
It depends on whether the bus is already here. Carpenter Bus generally keeps 200 or more new and used buses in stock, and a bus on the lot can often ship the same week or the next, almost always within a month. For a custom factory order, plan on 60 days to 9 months from the time you send your deposit, depending on chassis availability.
Work backwards from the date you need the bus. Start at the event or the first day of your program, ask your representative for the current build time on the chassis you want, then add a couple of weeks for graphics, lettering and transport. That puts the bus on your property ready to roll instead of arriving the week after you needed it.
Chassis availability is the part that moves, so the build time your representative quotes today is better than any range on a page. If your date is fixed, start the conversation early and ask what is already on the lot, since a stock bus skips the build entirely.
What do first-time bus buyers get wrong?
Five mistakes come up again and again, and every one of them is avoidable in a single phone call. None of them are about picking the wrong brand. They are about skipping a question early that becomes expensive later.
- Buying for the biggest trip. You pay for empty seats every week to serve a trip you take twice a year.
- Treating licensing as a detail. Buying a bus your drivers cannot legally drive stops the program before it starts.
- Skipping storage. The one feature that is hardest to add after delivery.
- Putting accessibility off. Adding it later usually means buying a different bus.
- Buying a used bus without a real inspection. Water damage is the expensive one, and it hides under the floor.
Frequently Asked Questions
What size bus do I need for 40 people?
For 40 people you are looking at a large bus, which Carpenter Bus defines as 31 passengers or more including the driver. Count your riders first. If 40 is your peak number and not your usual week, two smaller buses may serve you better, cost less to run, and keep you under the federal CDL threshold so more of your volunteers can drive.
If only a few people ride, can someone drive our bus on a regular license?
Licensing follows what the bus is built to carry, not how many people are on board that day. A bus designed for 16 or more people including the driver sits above the federal passenger threshold even when four people ride. Confirm your situation with your state licensing agency or a Carpenter Bus representative before you assign drivers.
Does a wheelchair lift reduce how many seats the bus has?
Yes. Each wheelchair position takes the floor space of regular seats, so a bus with lift positions seats fewer people than the same bus without them. Most Carpenter Bus buses can be set up with a rear or side wheelchair lift, and your representative can show you what a specific floor plan gives up and gains.
Why buy a bus instead of a 15 passenger van?
A purpose-built bus has dual rear wheels, a welded steel cage, a lower first step at the door, a center aisle and a higher roof. Those give it more stability than a standard 15 passenger van, and they make loading easier for older riders and children.
Can we put our current bus toward a new one?
Yes. Carpenter Bus buys well-maintained buses and vans nationwide and applies the market value toward any new or pre-owned bus or van in inventory. Fill out the form on the We Buy Buses page with your vehicle details, or email Henry Headden at [email protected]. There are criteria on year, mileage and capacity, and an offer carries no obligation.
Can our organization buy a bus if we are not a church?
Yes. Carpenter Bus sells to churches, senior care communities, private schools, daycares, hotels, shuttle operators, parking companies, nonprofits, corporations, municipalities and others. Warranty eligibility is the one thing that changes by organization type, so ask your representative which coverage your organization receives before you compare quotes.
What is your next step?
Write down the trip you take most often, the number of people on it, and who is willing to drive. Those three answers decide the bus. Bring them to a Carpenter Bus representative and they will show you what fits, what it will cost to run, and what is on the lot right now.
Start by comparing small buses for sale, the size roughly two-thirds of Carpenter Bus deliveries have been since January 2022. If your group has outgrown that, your representative will walk you up the sizes from there.
