Questions to ask before buying a used car

Before you decide, prepare clear, targeted questions for the seller. This guide groups practical questions to ask before buying a used car—so you can quickly uncover the real condition and avoid surprises.

Vehicle history

How many owners has it had, and how long have you owned it?
What was it mainly used for (city, highway, delivery, taxi, driving school)?
What’s the reason for sale?
Has the car ever been deregistered or unused for an extended period? Why?
Has the speedometer/instrument cluster ever been replaced or repaired?
How has the mileage progressed over the years (can you show a paper trail of invoices and service entries)?

Maintenance and wear items

Is there a service book and/or service invoices? Are they complete and legible?
When was the last routine service done (oil, all filters)?
When were the timing belt/chain and water pump replaced? If it has a chain, has the tensioner service ever been done?
Condition of brakes (discs, pads) and tires (DOT code, wear, season)? Is there an extra set of wheels/tires?
Has the transmission had service (fluid change, automatic transmission service) and the clutch? When and where?
Have the battery, alternator, radiator, or coolant pump been replaced recently?
Are any warning lights on the instrument panel? Are there recorded fault codes on diagnostics?
Have all factory service campaigns/recalls been completed?

Damage and current condition

Has the vehicle been in accidents or had major repairs? Which panels were painted or replaced?
Any signs of corrosion (wheel-arch edges, sills, floor pan/underbody, door edges, under seals)?
Any leaks of engine oil, coolant, transmission oil, or power-steering fluid?
What’s the condition of the suspension (noises, play in links/tie rods, shocks/struts)? What was last replaced?
Do all electrical systems work (A/C, heaters, parking sensors, multimedia, window regulators)?
What does the cabin smell like (damp, smoke)? Has the interior been kept pet-free?
Any cracks or damage to glass, lights, and plastics?
Is the full kit present: spare wheel/repair kit, jack, tow hook, warning triangle, first-aid kit?

Documents and ownership

Are you listed as the owner on the registration certificate? If not, what is your role in the sale?
Are two keys and all original documents available (registration, service book, invoices)?
Do the VIN numbers on the body match the documents?
Can you issue an invoice or a proper bill of sale with accurate details?
Are there any encumbrances on the vehicle (lease, loan, liens/notations)? Can you confirm this in writing?
When was the last technical inspection, and were there any notes?
Does the car come with extras and accessories (winter wheels, roof racks, floor mats)?

Test drive and independent check

Can we do a test drive from cold and at various speeds?
Do you mind if an independent mechanic or shop inspects the car?
Do you agree to paint thickness measurement and a computer diagnostics scan?
Can we put the car on a lift to check the underbody and leaks?

Finally: write down the answers, ask for proof (invoices, records), compare the story with the condition you see, and give yourself time to decide. Browse all guides
