What to check on a 1987 car
  • MOT history

    Check the reg below: its MOT history shows what has been failed or advised, and whether the mileage adds up.

  • Service history

    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.

  • Test drive

    Listen for knocks over bumps, check every warning light goes out, and make sure the gears and brakes feel right.

Other years

Most years have their own guide. The year is when the car was first registered (it’s on the logbook, or check the reg below).

Where this comes from: MOT figures are the DVSA’s anonymised results for every MOT test done in Great Britain during 2023–2025, grouped by the year each car was first registered. How many are on the road is from the Department for Transport’s vehicle licensing statistics. Known faults are from UK buying guides, in our own words, with links. How we score
