Check a used car before you buy

Run a registration check before you book a viewing: government MOT and DVLA facts, then a free preview of patterns worth asking about.

Illustrative car for inspection areas

A private seller’s photos and a quick walk around the car tell you how it looks today. They do not show what testers wrote on past MOT tests, whether the same note kept coming back, or how the recorded mileage moved between tests. Checking the registration first gives you a factual starting point before you travel or put down a deposit.

What to do before you book a viewing

Enter the registration above. The free check shows make, colour, fuel, year, the latest mileage on the MOT History file, and the names of areas testers wrote about. It does not show tax or current MOT expiry, and it does not confirm you have the right car.

If the lookup succeeds, you move into a free preview for that registration. The preview does not replace kicking the tyres. It summarises what the MOT file already suggests you should investigate: how many marked areas the engine found, whether the buyer position is lower concern, investigate, or significant concerns, and a short lead on what to ask the seller. You see counts and hooks, not the full pattern write-ups.

How the preview helps your buying decision

  • You learn whether the file is quiet or already pointing at repeated advisories, fail-then-pass sequences, or notes that later disappeared — before you negotiate.
  • You see which inspection areas are in scope on the model so you know where to look in person.
  • You get seller-question prompts drawn from this registration’s record, not generic car-buying tips.

When you are ready to go deeper, the buyer report opens the dated MOT timeline, verbatim pattern chronology, viewing tasks on the inspection model, and copyable questions for the seller. It still does not include finance, stolen, or write-off checks, and it is not a mechanic’s inspection.

What this check will not tell you

MOT tests are a legal minimum at a point in time. A pass does not prove the car is fault-free now. Silence in the file does not prove a clean history — only that nothing was recorded. Car Buyer Check does not score reliability, predict repair costs, or value the car.

Use the registration check to decide whether a viewing is worth your time and what to verify when you get there. If the preview surfaces patterns, carry those questions into the appointment; if the file is empty or very short, plan your own mechanical checks rather than assuming all is well.

Official sources

When should I run a registration check in the buying process?

Before you book a long-distance viewing or pay a holding deposit. It takes a minute and uses the same government MOT and DVLA data you would otherwise only discover on the day.

What does the free preview show that the initial lookup does not?

The lookup shows identity and licensing fields that were returned. We do not claim they are accurate. The preview adds a buyer-position summary, counts of marked inspection areas, and teasers for seller questions and map areas — enough to decide whether to open the full buyer report.

Does a clear preview mean the car is a safe buy?

No. A quiet file only means nothing problematic was recorded on past tests we can see. You still need an in-person inspection and, for high-value purchases, an independent mechanic.

Why pay for the buyer report if the preview is free?

The report unlocks the full MOT timeline, repeated and disappearing wording with original quotes where available, viewing tasks on the model, and complete seller questions — the material you use at the viewing and in price discussion.

Can I check a car I am only comparing on Auto Trader?

Yes. Run each registration you are comparing. The preview is per plate, so you can see whether one car’s file is already asking more questions than another before you arrange viewings.
