What to check on a 1984 car
  • Rust and structure

    Look underneath at the sills, floor, chassis rails and jacking points. Rust in the structure costs far more to fix than paint bubbles.

  • MOT-exempt isn’t roadworthy

    Cars over 40 don’t need an MOT, but they must still be safe. A voluntary MOT or a specialist inspection is worth the money.

  • Paperwork

    Old MOT certificates, bills and restoration photos show how it has been looked after. Check the logbook matches the car’s VIN and engine number.

  • Originality

    Changes from standard affect value and insurance. Ask what has been replaced or modified.

  • Insurance

    Classic insurance is often cheaper but may limit mileage and use. Get a quote before you buy.

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
