Check an AutoTrader listing before you buy.

AutoTrader is the UK's biggest used car marketplace, with listings from dealers and private sellers. Its price indicator tells you how the price compares with similar cars, but not whether this engine is reliable or which expensive jobs are due.

What to watch on AutoTrader

Medium risk

Price indicator

A “great price” compares the car with similar ads; it says nothing about the engine's known faults.

What to do

Weigh the price against the faults and maintenance due on this exact engine.

Medium risk

Dealer or private seller

Buying from a dealer gives you rights under the Consumer Rights Act; a private sale only has to match its description.

What to do

Check who is selling before you go, and ask for the service history either way.

High risk

Write-off categories

Cat S and Cat N cars can be listed legally, but repairs vary in quality and resale value is lower.

What to do

Ask whether the car has a write-off marker and ask for photos or invoices of the repair.

Does Carvizia work with the AutoTrader app?

Yes. Use the share button on the listing, copy the link and paste it into Carvizia, on your phone or computer.

Is AutoTrader's price indicator enough to judge a car?

It tells you how the price compares with similar cars on sale. Carvizia adds what it can't see: the engine's known faults, the maintenance coming up and what they cost, then a fair price that takes them into account.

Does the seller know I've analysed their listing?

No. Carvizia only reads the public listing; the seller is never contacted or notified.
