Pre-MOT Inspection Checklist for Morgan 4/4 Owners

These checks follow this Morgan 4/4's own most-recorded failure strings, starting with what a tester is most likely to flag on a Morgan 4/4.

• the steering — “steering rack gaiter missing or no longer prevents the ingress of dirt”

  With the wheels straight, rock the steering wheel gently with the engine off — more than about an inch of free play before the wheels move is worth investigating. Split rack gaiters are cheap to replace and commonly recorded.

• 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 lights — “rear fog lamp not working”

  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.

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 →
