Pre-MOT Inspection Checklist for MG Gs Owners

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

• the lights — “headlamp aim too low”

  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.

• 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.

• tyre pressures and valves — “tyre pressure monitoring system malfunctioning or obviously inoperative”

  Set the pressures to the figures on the door pillar, not the tyre wall, and check the valves do not hiss. A leaking valve is a two-minute fix that fails a test.

Derived from the DVSA failure strings testers recorded for the MG Gs. A check that finds nothing means the item is likely fine, not that the test is guaranteed.

Where the MG Gs is most common

Across every Gs model year on record (2016–2019): 4,096 MG Gs cars tested in a recordable postcode area, across 9,518 tests. Cardiff (CF) has the most, with 316 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 Gs 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 →
