What to check on a 1989 car
- MOT history
Check the reg below: its MOT history shows what has been failed or advised, and whether the mileage adds up.

Look for regular servicing and receipts for big jobs like a cambelt or clutch.
- Finance and write-offs
MOT records don’t show outstanding finance or insurance write-offs. A history check does.
