Expert verdict

Brakes: 1.8× the national share

Brakes make up 37.8% of everything recorded on the 2015 Morgan 4/4, against 20.9% nationally — 16.9 points above. Have the discs and pads measured rather than glanced at, and ask whether the handbrake holds on a slope.

Where the Morgan 4/4 is most common

Across all 4/4 model years on record (2000–2018): 1,372 Morgan 4/4 cars tested in a recordable postcode area, across 3,089 tests. Ashford (TN) has the most, with 93 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 Morgan 4/4 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 →

Before your test

Three checks worth doing on a 2015 4/4

These are not generic tips — they are the faults recorded most often on this exact model, rewritten as things you can check yourself. All three take about ten minutes and cost nothing.

  1. Check the lights 1.7% of tests

    “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.

  2. Check the steering 1.7% of tests

    “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.

  3. Check the exhaust and emissions 0.9% of tests

    “catalyst emissions Lambda reading after 2nd fast idle outside specified limits”

    Listen for a blow at idle and have someone rev it gently. Then look at the tailpipe smoke: blue is oil, white when warm is coolant, black is over-fuelling. Any of those and the emissions test is the least of it.

Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.

What it costs to get a 2015 4/4 through its MOT

Across the 10 items that are recorded most often on this model, the average repair comes to £46–£132 — and 31% of those repairs are parts that cost under £30.
