Expert verdict
Brakes: 2.0× the national share
Brakes make up 41.7% of everything recorded on the 2017 Morgan 4/4, against 20.9% nationally — 20.8 points above. Have the discs and pads measured rather than glanced at, and ask whether the handbrake holds on a slope.
- Beats its own age and mileage. Once you allow for how old and how far these cars have been driven, the expected pass rate is 86.0% and this one manages 98.4% — 12.4 points ahead of what its age and mileage predict.
- When it fails, it costs. Only 33% of this model’s typical repairs come in under £30 in parts — the failures here tend to be the kind that need a garage rather than a bulb.

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 →

What fails a 2017 4/4
Everything a tester recorded on this vehicle, grouped into the inspection sections that produced it. The notch on each bar is the national share, so you can see at a glance whether this car is unusual or just ordinary.
A test can record several items, so these percentages do not add up to 100%. The exact strings, with prices, are in the full DVSA record at the bottom of this page.
Before your test
Three checks worth doing on a 2017 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.
-
Check the steering 1.6% 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.
-
Check the brake pipes 0.8% of tests
“flexible brake hoses slightly chafed”
Brake pipes run under the car, usually in front of the rear wheels. Flaking or crusty metal is what fails; a light dusting of surface rust does not. Worth asking a garage to look while it is on a ramp.
-
Check the wipers and washers 0.8% of tests
“washers provides insufficient washer liquid”
Run the wipers with the screen wet: they should clear it in one sweep without smearing or juddering. Top the washer bottle up and check both jets hit the screen.
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 2017 4/4 through its MOT
Across the 5 items that are recorded most often on this model, the average repair comes to £54–£134 — and 33% of those repairs are parts that cost under £30.
