Pre-MOT Inspection Checklist for BMW 320 Owners

These checks follow this BMW 320's own most-recorded failure strings, starting with what a tester is most likely to flag on a BMW 320.

• the windscreen — “windscreen damaged”

  Check the driver’s side of the screen within the swept area for chips and cracks; anything larger than 10mm in the driver’s central view is a fail. Most chips can be resin-repaired for far less than a new screen.

• the tyre tread — “tread depth below requirements of 1.6mm”

  Check all four tyres cold, including the inner shoulder where wear hides — 1.6mm across the central three-quarters is the legal limit, and most testers fail at 1.6mm without argument.

• the brakes — “brake pads less than 1.5 mm thick”

  Look through the spokes of each wheel at the pad — less than 3mm of friction material, or a lip on the disc edge, is the usual failure. Check the handbrake holds on a slope with a few clicks, not at the top of its travel.

Where the BMW 320 is most common

Across every 320 model year on record (2003–2023): 63,489 BMW 320 cars tested in a recordable postcode area, across 129,146 tests. Birmingham (B) has the most, with 2,243 cars tested there. Cars are counted by the postcode area of the MOT station, so this is where they were tested, not necessarily where their owners live.

The twenty areas with the most BMW 320 cars in the record, sorted by car count — sort the columns for a different question. Cars tested at a station whose postcode area could not be resolved are counted in the model's total but in no area, so the shares add up to slightly under 100% even across every area, and an area's cars are a subset of the model's. Pass rate is blank below 30 tests in an area, where a percentage is noise rather than a finding. How this model's pass rate varies by postcode →
