Expert verdict
Tyres: 1.6× the national share
Tyres make up 31.4% of everything recorded on the 2015 Ford Mustang, against 19.8% nationally — 11.6 points above. Check all four tyres yourself, including the inner shoulders, and look at the date stamp — a tyre can pass on tread and still be six years old.
- 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 82.1% and this one manages 88.4% — 6.3 points ahead of what its age and mileage predict.
- When it fails, it costs. Only 28% 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.

What fails a 2015 Mustang
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 2015 Mustang
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 windscreen 1.9% of tests
“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.
-
Check the wipers and washers 1.3% of tests
“wipers does not clear the windscreen effectively”
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.
-
Check tyre pressures and valves 0.9% of tests
“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.
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 Mustang through its MOT
Across the 10 items that are recorded most often on this model, the average repair comes to £40–£98 — and 28% of those repairs are parts that cost under £30.

What testers noted without failing the car
Advisories are the early warnings — the same parts a year or two before they fail. Reading them is how you tell a car that has been maintained from one that has been patched.

|---|---|---|---|
| Tread depth below requirements of 1.6mm Tyres | Advisory | 13.8% | £45–95 |
| Brake discs in such a condition that it is seriously weakened Brakes | Advisory | 6.5% | £45–110 |
| Brake pads less than 1.5 mm thick Brakes | Advisory | 4.5% | £18–45 |
