What the MOT record will not tell you
Knowing that Mercedes-Benz AMG failures cluster around tyres and road wheels tells you what to inspect. It tells you nothing about whether the car is legally safe to buy. An MOT records that a car met a minimum standard on the day it was tested. It does not check the engine, clutch or gearbox, and it says nothing at all about the car's legal and financial history. On a 3.6-year-old average example those are the risks that cost real money:
- Outstanding finance. If money is still owed against the car, the lender may retain an interest in it after you have paid the seller.
- Insurance write-off history. A recorded Cat S or Cat N marker is permanent and affects safety, insurance and resale — and it does not appear on the V5C.
- Stolen markers. A vehicle recorded as stolen can be seized even from a buyer who bought it in good faith.
- Mileage history. Recorded readings that do not move consistently between tests are the clearest sign of a clocked car.
- Previous keepers. An unusual number of owners for the age of the car is worth asking about.
A Carpeep car history check reports all of those against the registration, plus tax status, import and export markers, scrapped status and the vehicle identity details, in one £15 report.
