Expert verdict
Lamps & electrics: 1.9× the national share
Lamps & electrics make up 23.4% of everything recorded on the 2011 Ford Mustang, against 12.2% nationally — 11.2 points above. Walk round the car with the lights on before the test: bulbs, indicators and number-plate lamps are the cheapest failures to prevent and among the most common.
- 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 75.9% and this one manages 82.3% — 6.4 points ahead of what its age and mileage predict.
- Failures here tend to be cheap ones. 74% of the repairs this model fails on cost under £30 in parts. The pass rate matters less than what a bad afternoon at the test centre actually costs you.

What fails a 2011 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 2011 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 lights 4.2% of tests
“registration plate lamp(s) inoperative in the case of multiple lamps or light sources”
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.
-
Check the battery 3.4% of tests
“battery(ies) insecure”
Check the battery is secure and its terminals are clean and tight — a loose battery is a fail on its own, and a weak one shows up as slow cranking on a cold morning.
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 2011 Mustang through its MOT
Across the 10 items that are recorded most often on this model, the average repair comes to £16–£44 — and 74% of those repairs are parts that cost under £30.
