Buying Guides
What to look for when buying a used BMW
Model-specific advice for UK buyers — common issues, MOT history, and fair prices.
By CarSwipe Team ·
BMWs are among the UK's most popular used buys — but not all models are equal.
Check the service history
Full BMW service history protects resale value. Gaps suggest deferred maintenance.
Known issues by era
- N47 diesel engines (pre-2014): timing chain concerns — listen for rattles on cold start.
- B48/B58 petrol: generally robust; check for coolant leaks.
- Electronics: iDrive glitches are common; test every screen function on a test drive.
MOT and HPI
Always run an HPI or similar check. Filter for insurance write-offs on CarSwipe if you want a clean history only.
