Pre-MOT Inspection Checklist for MG Zs Trophy Owners

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

• the coil springs — “coil spring fractured or broken”

  Look up inside each wheel arch with a torch, all the way round the spring. A snapped spring usually breaks at the very bottom coil, where a quick glance will not reach.

• 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 lights — “registration plate lamp(s) inoperative in the case of multiple lamps or light sources”

  Switch everything on and walk round the car: both headlamps on dip and main, every indicator, both brake lights, reverse, fog and the two number-plate lamps. A bulb is a few pounds and a five-minute job.

Where the MG Zs Trophy is most common

Across every Zs Trophy model year on record (2021–2023): 4,493 MG Zs Trophy cars tested in a recordable postcode area, across 6,024 tests. London (NW) has the most, with 172 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 MG Zs Trophy 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 →
