How to Check a Used Car's History Before You Buy

The check that saves you thousands

A used car can hide expensive secrets: outstanding finance, a past write-off, or a wound-back odometer. A history check exposes these before you pay — it's the single most important step in a private car purchase. Here's how to do it.

1. Match the identity

Confirm the VIN (on the windscreen, door frame and under the bonnet) and the registration document match each other and the seller's name and address. Any mismatch is a serious red flag.

2. Run a history/data check

Use a paid vehicle-history report — the small fee is trivial next to the car. It reveals:

• Outstanding finance — if money is still owed, the lender can repossess the car even after you've paid the seller. Never skip this.
• Write-off / total-loss records — cars written off after accidents or floods may be unsafe or worth far less.
• Stolen status — a match against police databases.
• Mileage history — inconsistent readings across MOT/service records suggest odometer tampering ("clocking").
• Plate/colour changes that don't add up.

Tools vary by country — e.g. Carfax/AutoCheck (US & Canada), HPI/RAC (UK), and official registries elsewhere. Cross-check the free government MOT/inspection history too.

3. Verify mileage independently

Compare the odometer against service stamps, MOT/inspection records and general wear (steering wheel, pedals, seats). A 30,000-mile car with a worn-out interior isn't a 30,000-mile car.
