How to Inspect a Used Car Before Buying: Full Checklist

To inspect a used car before buying, see it in daylight with a cold engine, check that the chassis number matches the papers, go over the body, engine bay and interior, then test drive it for at least 20 minutes. If it passes your checks, pay a mechanic you trust to confirm before any money changes hands.

What should I ask before going to see the car?

A few questions by phone or WhatsApp save wasted trips:

• Is the car registered in your name? If not, whose?
• How long have you owned it, and why are you selling?
• Has it been in an accident or a flood?
• Which papers can you show, and are they originals?
• Can I see it before the engine has been started that day?
• Can I bring a mechanic?

Ask for a photo of the dashboard with the engine running. Compare the asking price with similar used cars for sale: a price far below the others is a warning, not a bargain.

How do I check that the papers match the car?

Most expensive mistakes start here, not under the bonnet.

• Find the chassis number on the car (often at the base of the windscreen, on a door pillar sticker or on a plate in the engine bay) and compare every character with the papers.
• The name on the papers should match the seller's ID. If someone else owns the car, that person has to be involved in the sale.
• Look for signs of tampering: scratched or re-stamped numbers, plates fixed with fresh rivets or welds, corrections on the documents.

In Kenya

NTSA announced that its electronic logbook (eLogbook) would go live on 10 June 2026 for registration transactions, including transfers of ownership, with owners viewing and downloading it from their eCitizen account. The NTSA service portal also has a public Verify Logbook tool to check the validity of a logbook; its instructions refer to the code generated by scanning the logbook's QR code and to the chassis number. Do this check before paying anything. Our guide on how to transfer car ownership in Kenya explains what happens after the sale.

In Nigeria

Vehicle papers and the change of ownership follow a separate procedure, covered in our guide to vehicle ownership transfer in Nigeria. Read it before the viewing so you know which originals to ask for.

What should I look for on the outside?

• Uneven gaps between panels, or a paint shade that changes from one panel to the next: signs of accident repair
• Overspray on rubber seals, lights or trim
• Rust bubbles on the sills, wheel arches and lower doors
• Tyres worn unevenly across the tread, which can point to alignment or suspension problems
• Chips or cracks in the windscreen, and any light that does not work
• Fresh oil, coolant or fuel drips underneath (bring a torch)

Signs of flood damage

• A damp, musty smell, or strong air freshener hiding one
• Silt or watermarks under the carpets, in the boot under the spare wheel, or along the seat rails
• Rust on seat bolts and pedal mounts, which rarely rust on a car that has stayed dry
• Headlights with a line of condensation inside

What should I check under the bonnet?

Insist on a cold start. A warm engine hides starting problems and some leaks, so be wary if the bonnet is already hot when you arrive.

• Pull the dipstick: a milky, creamy look can mean coolant is mixing with the oil, an expensive repair.
• Check the coolant level, and look for an oily film on it.
• Look at belts and hoses for cracks or bulges.
• Check the battery terminals for heavy corrosion.
• Watch the exhaust at start-up. Blue smoke that persists suggests the engine burns oil; thick white smoke that does not clear can point to coolant; black smoke suggests a fuel mixture problem.
• Listen for knocking, ticking or whining once the engine is running.

What should I check inside the car?

• At ignition, the dashboard warning lights should come on briefly and then go out. A light that never comes on at all may have been disconnected.
• The air conditioning should blow cold within a few minutes.
• Try every window, lock, mirror, seat adjustment, wiper, the horn and the radio.
• Compare wear on the steering wheel, gear knob, pedals and driver's seat with the mileage shown. Heavy wear and a low mileage do not go together.
• Seat belts should pull out smoothly, retract and lock.

How long should the test drive be?

At least 20 minutes, on a mix of roads: slow traffic, a rougher stretch and, if possible, a faster road. Let the seller drive first if you prefer, then take the wheel yourself.

• The car should run straight without pulling to one side, and brake straight without vibration.
• An automatic gearbox should change smoothly, without jerks or delays; a manual should not slip or crunch.
• Listen for clunks over bumps and for noises when turning at full lock.
• The temperature gauge should settle in the middle and stay there.
• Afterwards, look underneath again for drips.

Should I pay a mechanic to inspect the car?

Yes, once the car has passed your own checks. A mechanic you trust will spot old repairs, worn parts and stored fault codes that you cannot. Workshops with a diagnostic scanner can read the engine computer in minutes. The fee is small next to the cost of buying the wrong car, and a seller who refuses an independent inspection has given you your answer.

Which red flags should end the viewing?

• The papers are not in the seller's name and the owner cannot be reached.
• The chassis number does not match the papers, or looks tampered with.
• The engine was warm when you arrived, despite your request.
• The seller pushes for a deposit "to hold the car".
• The price is far below similar cars, with a story about an urgent move abroad.
• The meeting place keeps changing, or the seller wants to finish the deal at night.

Payment comes last, once the papers and the car match. Our guide to avoiding online scams in Nigeria and Kenya explains how to pay without being caught out.
