Citroen CX buying guide: what to check
What goes wrong on a used Citroen CX, year by year: known faults from UK buying guides and what to check before you buy one.
The 1981 Citroen CX
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 Citroen CX as a whole.
What to check on a 1981 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.

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
