Quick Answer
Walk away from a used car if the seller won't show the V5C, the VIN doesn't match, the price is unrealistically low, they pressure you to pay cash fast, the mileage doesn't match the MOT record, or a history check reveals finance, theft or an undisclosed write-off.
Walk-away red flags
- No V5C, a photocopy only, or details that don't match the seller
- VIN or engine number that doesn't match the paperwork
- Mileage that conflicts with the MOT history
- Pressure to pay a deposit or cash before viewing
- Seller wants to meet somewhere other than their home address
- A price far below similar cars for no good reason
Trust the checks over the story
A convincing seller can explain away almost anything. Data can't be talked around: if a history check shows outstanding finance, a theft marker or a hidden write-off, walk away regardless of how good the deal or the seller seems.
Check before you commit
Let the data decide — reveal finance, theft and write-off issues on any reg before you buy.
Check before you commitFrequently Asked Questions
Is a cheap price always a bad sign?
Not always, but an unusually low price with a rushed sale is a classic warning sign of a stolen, cloned or problem car. Let the checks — not the bargain — decide.
Should I walk away over a write-off?
Not necessarily if it's disclosed and priced accordingly. But an undisclosed write-off you only found via a check is a trust red flag — proceed with real caution or walk away.
