Mileage benchmarks — BMW 5 Series
From ages 3 to 5, average mileage on a BMW 5 Series rises from around 30,000 miles to 50,000 miles — about 10,000 miles a year, which is in line with the UK average use pattern. A specific car well below or above these averages warrants extra scrutiny — very low mileage on an older car can mean infrequent maintenance just as easily as low use.

Pre-purchase checklist for a BMW 5 Series
- Pull the MOT history first. A pattern of repeat advisories in the same category (e.g. suspension knock noted on three tests in a row) usually means a deferred repair waiting for you.
- Sanity-check the mileage. Compare what’s on the odometer with the readings logged at each MOT. Any backward step or implausibly large jump is a red flag.
- Inspect the top failure points yourself. For this model the cluster is lamps, reflectors and electrical equipment and suspension — both are easy to assess in a short test drive.
- Ask for the last service record. A BMW with consistent dealer or independent service stamps will normally outperform the model-average pass rate of 77.8%.
