25 Questions to Ask When Buying a Used Car
Twenty-five questions for a used car viewing: service history, accident and repair record, previous owners, odometer accuracy, the faults the seller has been living with, and whether the title and registration are clean. Written for buying from a private seller or a small lot.
The questions
Open any question for the note
How long have you owned the car, and what did you mainly use it for?
Why ask it
An easy opener that sets up everything else. A car used for a short highway commute is in a different condition from one used for city delivery work at the same mileage. A seller who has owned it only a few months either bought a problem or is reselling for profit.
Why are you selling it now?
Why ask it
Listen for whether the reason has anything to do with the car. Growing family, moving abroad, a company car arriving: all fine. Answers that drift, or change between the phone call and the driveway, usually mean there is a repair bill they decided not to pay.
How many owners has it had before you?
Why ask it
Numbers matter less than the pattern. Two long ownerships beat five short ones, because a car that changes hands every year is often being passed along ahead of a fault nobody wants to fix. Fleet or rental history is worth knowing too, since it usually means hard, unsentimental use.
What does the odometer read, and does that match the service and inspection records?
Why ask it
The number on the dash is the easiest thing on a car to falsify. Cross-check it against dated service stamps and past inspection reports, then against physical wear. Shiny worn pedal rubbers, a polished steering wheel and a sagging driver's seat on a low-mileage car do not agree with each other.
Can I see the full service history and the receipts that go with it?
Why ask it
Paper you can hold is the point. A folder of dated invoices naming the garage and the work is strong evidence; "I did it all myself" with nothing written down means you are buying the timing belt, transmission service and coolant change blind and should assume none were done.
What has been repaired or replaced while you owned it?
Why ask it
This is where you learn whether it has needed a lot of small attention. A short list of consumables reads well. A long list of electrical fixes, or the same part replaced twice, points at a fault that was never actually found.
Is anything not working right now, however small?
Why ask it
What the seller volunteers before you point at anything is the honest bit of the whole viewing. A dead window motor disclosed up front is reassuring; "absolutely nothing" on a ten-year-old car is a reason to spend more on an inspection, not less.
Has it ever been in an accident, and which panels or structural parts were repaired?
Why ask it
Sellers minimise this as a bump, so push past the summary to which specific parts were replaced and whether the frame or unibody was pulled straight. Structural repair shows itself later as uneven tire wear, doors that no longer seal and paint that lifts along a seam.
Has it ever been flooded, stolen and recovered, or written off by an insurer?
Why ask it
Branded titles get laundered by re-registering the car in another state, so the paperwork can look clean when the history is not. Check the physical version yourself: a damp smell, silt in the seatbelt tracks, rust on bolt heads under the carpet, mismatched screws around the ignition.
Can you show me a vehicle history report, and can we read it together?
Why ask it
Reading it in front of the seller is the useful part, because it lets you ask about the gaps as they appear: the year with no record at all, the state it briefly moved to, the mileage entry that dropped. A seller who wants you to buy the report yourself may already know what is in it.
Is the title in your name, and is there any finance or lien still outstanding?
Why ask it
A lien means the lender, not the seller, effectively controls the car, and paying the seller does not clear it. If they cannot produce the title in their own name at the viewing, there is nothing to buy yet, however good the car looks.
Are you selling it for yourself, or on behalf of someone else?
Why ask it
Traders sometimes pose as private sellers to sidestep the protections a dealer legally owes a buyer. The signs are a name on the title that is not the person in front of you, a meeting point that is not their home, and two or three other cars for sale at the same address.
Are there any open recalls, and has the work been done?
Why ask it
Recall repairs are free at a franchised dealer, so an outstanding one usually means the car has been kept away from dealers entirely. You do not have to rely on the answer: the manufacturer or the safety regulator will tell you from the VIN in a minute.
Are there unpaid tickets, tolls, or violations attached to the car?
Why ask it
Depending on where you register, unpaid tolls and parking fines can follow the plate or quietly block the transfer. It is a small question that occasionally saves a wasted trip to the licensing office and an argument about who owes what.
Is the registration current, and when does it expire?
Why ask it
Expired registration tells you the car may not have been legally driven for a while, which changes what the test drive means and what fees land on you at transfer. It also occasionally reveals that the seller cannot register it, which is a different problem entirely.
Has the car been sitting unused for any long stretch?
Why ask it
Standing still damages cars in ways mileage does not: flat-spotted tires, seized brake calipers, perished belts, a battery that will not hold charge, mice in the airbox. Ask when it was last driven any real distance, not just when it last started.
Are both keys and all remotes here, and do they lock and start the car?
Why ask it
Test them rather than accept the answer. A second key with immobiliser coding often costs several hundred at a dealer, so a missing one is a fair price adjustment. A single heavily worn key on a car sold as low-mileage is also worth a second thought.
Have any modifications been fitted, and do you still have the original parts?
Why ask it
Lowered suspension, a remapped engine or an aftermarket exhaust tell you something about how the car has been driven, and they can raise your insurance or void what is left of a powertrain warranty. A seller who kept the stock parts in the garage is usually the careful kind.
What fuel economy did you actually get, and what did insurance and tires cost you?
Why ask it
Real numbers from this car beat the manufacturer's figure, and running costs are where a cheap car turns expensive. Large wheels, run-flat tires, premium fuel and a model in a high insurance group can each add more per year than you saved on the purchase.
Which jobs fall due next: timing belt, clutch, brakes, tires?
Why ask it
You are asking for next year's bills. An owner who knows the model will name two or three by mileage or date; "nothing for ages" usually means they never checked the service schedule. Belts and clutches are the ones that turn a bargain into a four-figure repair.
Which parts of the car would you fix first if you were keeping it?
Why ask it
Phrased this way it is awkward to answer with "it is perfect", so most sellers name a couple of real things. Whatever they list is your immediate repair budget, and how readily they answer tells you how much of the rest to believe.
Can I take it on a long test drive from cold, including faster roads?
Why ask it
A cold start reveals smoke, rattles and rough running that vanish once warm, and highway speed reveals vibration, pulling and gearbox behaviour that a lap of the block hides. If the engine is already warm when you arrive, ask why, and come back another time.
Can I have my own mechanic inspect it before I commit?
Why ask it
This is the question that ends bad deals. A seller with nothing to hide agrees or offers to meet you at the shop. Refusal, urgency about another buyer, or insistence that you use their mechanic tells you what the inspection would have found.
Does it come with any warranty or return period, and what does that exclude?
Why ask it
Ask what is not covered rather than what is. Many used-car warranties pay for parts but not labour, cap the claim below the cost of the repair, or lapse if you service the car anywhere but their shop. Private sales normally come with nothing, which is worth hearing out loud.
How did you arrive at the asking price?
Why ask it
The answer sorts sellers into two kinds. One has compared listings for the same year, mileage and trim and can defend the number. The other picked a figure they need for their next car, and that figure moves once you have found two or three things wrong.
Buying a used car well
Practical guidance for the conversation itself
Before you leave the house
Get the VIN over the phone
Ask for the VIN and the plate before you drive anywhere. With those you can check open recalls with the manufacturer, pull a history report, and confirm the year and trim actually match the advert. Sellers who will not give you the VIN of a car they are advertising are telling you something.
Know the model's known faults
Spend twenty minutes on owner forums for that engine and gearbox combination. Every model has two or three failures that turn up at a predictable mileage, and knowing them lets you ask a specific question instead of a general one.
Line up an inspection first
Find an independent shop near the seller and ask what a pre-purchase inspection costs before you view. Having somewhere to take the car turns your inspection question from a hypothetical into an appointment, which is much harder to deflect.
Arrange to see it in daylight, dry
Rain and dusk hide paint mismatch, ripples in a repaired panel and fluid on the ground. If the only slot offered is after dark, treat that as a reason to wait rather than a scheduling detail.
Order to work through at the viewing
- 1Touch the hood before anything else. If the engine is already warm, you have lost the cold start, which is where most engine and exhaust problems announce themselves.
- 2Walk the car once without talking. Look along each side for light catching a panel differently, check panel gaps left against right, and see whether all four tires are the same brand and wear evenly.
- 3Open and close every door, window and the trunk. Cheap to test, expensive to fix, and a good early read on how the car has been treated.
- 4Look under the carpets and the spare wheel cover for damp, silt or fresh sealant, then check the oil and coolant while the engine is still cold.
- 5Drive it: cold start, stop-start traffic, a rough surface, then a sustained faster road. Turn the radio off. Brake hard once where it is safe to feel for pulling or shudder.
- 6Go through the paperwork last, sitting down, with the history report open. Names, dates and mileage entries should agree with each other and with the car you just drove.
- 7Leave without agreeing anything. Every serious problem you later found, you found after you stopped standing in front of the seller.
Answers that should end the viewing
- The title is not in the seller's name, or it is not present at all.
- You may not take the car to an independent mechanic.
- There is pressure about another buyer who is arriving shortly.
- The seller wants a deposit before you have driven the car.
- The mileage story and the wear on the pedals, seat and steering wheel do not match.
- A repair was clearly done but the seller cannot say who did it or why.
- The meeting place is a parking lot rather than a home or a business address.
Negotiating and paying
Negotiate from findings, not from feelings
Name the specific items: tires at the wear bars, a service due in two thousand miles, one key missing. A list of costed jobs moves a price. A general request for a discount usually does not.
Do not let a deposit commit you
Deposits are often described as refundable and then are not. If you want to hold the car, put the terms in a text message the seller replies to, so both of you have the same words in writing.
Pay in a traceable way
Bank transfer or a cashier's check at the bank leaves a record of who received the money. Insist on a signed bill of sale with the VIN, mileage, price, date and both names, and take a photo of the title and the seller's ID with it.
Handle the transfer yourself, promptly
Do not rely on the seller to file anything. Register and insure the car in your own name straight away, because unpaid tickets and liability in the gap between sale and registration tend to land on whoever the record still names.
