BMW 7 Series common problems and MOT failures
What goes wrong on a used BMW 7 Series, year by year: known faults from UK buying guides, the parts flagged at MOT more than on other cars (from 10,232 MOTs done during 2023–2025), and what to check before you buy one.
The 1984 BMW 7 Series
Our MOT figures start with cars first registered in 1990. There are no known faults on record for this year in the UK buying guides we use, so the rest of this page covers the BMW 7 Series as a whole.
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.

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
