Questions to Ask About Used Cars
Questions for the person selling a used car, whether that is a private owner on a driveway or a salesperson on a forecourt. They run from the car's history through its condition and paperwork to the price, in the order a viewing usually goes.
The questions
Open any question for the note
How long have you had it, and what did you use it for day to day?
Why ask it
A car that did twelve miles of city stop and start each day has a different kind of wear from one that sat on a highway for an hour each way. Short cold journeys are harder on an engine and exhaust than the mileage alone suggests.
Why are you selling it?
Why ask it
Most answers are ordinary: a new job, a baby, a move. What you are listening for is a reason that does not fit the car, such as selling a family car after four months, or a story that changes when you ask again later in the visit.
Who owned it before you, and is the title in your name?
Why ask it
A seller whose name is not on the title may be trading on someone else's behalf without saying so, which leaves you with no recourse if the car turns out to be misdescribed. Check the name and address against their ID before anything else.
What's the mileage now, and roughly how much did you add each year?
Why ask it
The yearly figure is easier to sanity check than the total, and it should match the service stamps and inspection records. A car that suddenly stops accumulating miles for two years is either a project, a garage ornament, or has had its records reset.
Can I see the service records and the receipts?
Why ask it
Paper beats claims. Stamps from a mix of garages are fine, but you want dates and mileages that climb steadily. A missing two or three year stretch is worth more attention than an old car with a thin book, because that is usually when something expensive was avoided.
What work has been done in the last year, and who did it?
Why ask it
Recent work tells you what was failing. A new battery and alternator is reassuring. A new head gasket at moderate mileage says the engine overheated once, and you want to know why. Work done by a friend with no invoice is work you cannot verify.
What needs doing next, and what have you been putting off?
Why ask it
Almost every used car has a job pending, and an owner who names one, brake discs at the next service, a slow leak from a rear shock, is being straight with you. An owner who says nothing at all needs doing on a ten year old car is either inattentive or not telling you.
Has it ever been in an accident, however minor?
Why ask it
Ask it as a plain yes or no and then let the silence sit. Small repairs are not disqualifying, but undisclosed structural repair is, and the answer here is what you compare with the panel gaps, the paint depth and a history check afterwards.
Has any panel been repainted or replaced?
Why ask it
Repaint is normal after a scrape and easy to check by looking down the side of the car in daylight for a mismatch in texture or shade. An answer of no on a car with obvious overspray on the door seals tells you how much the rest of the answers are worth.
Are there any warning lights on now, or any that come and go?
Why ask it
Intermittent lights are the ones sellers forget to mention, and the ones that fail an emissions test later. If a dashboard is completely clear on an older car, check that the bulbs illuminate at all when you turn the key.
When were the tires and brakes last replaced?
Why ask it
Both are near term costs you can put a number on before you negotiate. Four mismatched budget tires on an otherwise cared for car usually mean the last owner was economizing, which is worth knowing before you buy their maintenance decisions.
Has the timing belt or chain been done, and at what mileage?
Why ask it
On engines with a belt this is a scheduled job that costs real money and destroys the engine if it is skipped. A seller who does not know whether their car even has a belt has not been reading the service schedule they say they followed.
Where has it been kept at night, and has it lived near the coast or on salted roads?
Why ask it
Storage and geography explain corrosion better than age does. Cars from areas that salt roads in winter rust from underneath, so this answer tells you where to point your torch on the sills, subframe and brake lines.
Does everything electrical work: windows, air conditioning, heated seats, screen?
Why ask it
Ask, then test every switch yourself while you are sitting in it. Air conditioning that only blows cool is a regas at best and a compressor at worst, and a seller who says it just needs gassing is quoting you the cheap version of an unknown fault.
Are there two keys, a spare wheel or kit, and the handbook?
Why ask it
A missing second key is a genuine cost on a modern car and a small clue about how the car was kept. Missing handbooks and service portfolios often go with a history that has been tidied up.
Has it ever failed a roadworthiness or emissions test, and what for?
Why ask it
Past failures are a map of the car's weak points, and in many places the record is public, so this is a question you can verify afterwards. Repeated advisories on the same item mean it was never actually fixed.
Is there any outstanding finance or lien on it?
Why ask it
If money is still owed against the car, the lender can have a claim on it after you pay. Ask directly, then check with a paid history search rather than relying on the answer, because this is the one problem that can cost you the whole car.
Can I take it to my own mechanic for an inspection?
Why ask it
The answer matters more than the inspection. A seller with nothing to hide will agree or offer to meet you at a garage. Refusal, delay or an insistence that their own mechanic has already checked it is the clearest reason to walk away.
Can I start it cold and drive it on the highway as well as in town?
Why ask it
A warmed up engine hides smoke, rattles and hard starting, so arrange to arrive before it has been run. Highway speed is where you feel vibration through the wheel, a slipping gearbox and wind noise from a badly refitted door.
What's the lowest you'd take, and does that assume the work it needs is mine to pay for?
Why ask it
Naming the pending work in the same sentence as the price stops the negotiation from being about the sticker alone. If they will not move at all, ask what comparable cars with a full history are selling for, and be ready for them to have that number too.
Buying a used car from a stranger
Practical guidance for the conversation itself
Before you go and see it
- 1Ask for the registration number or VIN by message and run a paid history check yourself. It covers write off records, mileage anomalies, outstanding finance and theft.
- 2Look up what the same model, year and mileage is actually selling for, not what other sellers are asking.
- 3Read an owners forum for that specific engine and gearbox combination and note the two or three known faults. Then you know which noise matters.
- 4Ask by message whether they are a private seller or trading. Traders posing as private sellers are avoiding the consumer protections that come with a business sale.
- 5Arrange to see it in daylight, dry weather if possible, and with the engine cold.
What to do while you are standing next to it
- Crouch at each corner and look down the body line. Ripples, mismatched shade and uneven panel gaps are repair, whatever you have been told.
- Open and shut every door, and check the rubber seals for overspray.
- Pull the oil dipstick and look at the coolant. Mayonnaise coloring in either is a reason to stop.
- Lift the boot carpet and check the spare well for damp, rust and repair welds.
- Look at the wear on the pedals, gear knob and steering wheel and ask yourself whether it matches the mileage on the clock.
- Start it and listen before touching the accelerator, then check the exhaust for smoke as it revs.
Reasons to end the visit
- The name on the title does not match the person selling, and there is no explanation you can verify.
- You are told the car cannot be inspected independently, or cannot be driven today.
- The seller pushes for a deposit before you have seen the paperwork.
- The mileage or the story changes between the advert, the phone call and the driveway.
- You are asked to pay in cash for a reason that is about their convenience, or to send a transfer before collection.
Negotiating without theater
Price the faults, not your feelings
Two tires, a service and a set of discs is a number you can say out loud. That moves a conversation far better than an opening offer picked to be insulting.
Be willing to leave and come back
Sellers who will not move on the day often call within a week, particularly if the car has been advertised for a while. Ask how long it has been for sale.
Get the description in writing
For a private sale, a short receipt naming the car, the mileage, the price and the words sold as described, signed by both of you, is worth having if something significant turns out to have been hidden.
