Should you buy a used BMW 320I SE Auto?

The BMW 320I SE Auto has an overall MOT pass rate of 89.0% across 724 real MOT tests — comfortably above the UK average, which puts it among the more reliable models on UK roads.

On the safety side, the most frequently flagged dangerous fault is tyre tread depth below requirements of 1.6mm. Dangerous faults cause an immediate MOT failure and mean the vehicle is not roadworthy until repaired. If you're viewing a BMW 320I SE Auto with an expired or recently passed MOT, ask the seller whether any dangerous faults were found and fixed during the last test.

A typical BMW 320I SE Auto owner drives around 4,921 miles per year. If the car you're looking at is significantly above this, expect more wear on suspension, brakes and tyres. If it's well below, the vehicle may have been sitting unused — check for perished rubber, corroded discs and stale fluids.

Before committing to a purchase, we recommend running a full vehicle history check on the specific car. This will reveal any outstanding finance, stolen markers, write-off history and mileage discrepancies that the seller may not disclose — and that the MOT data alone can't tell you.
