percentage points below average
Ranked on pass rate the MGF sits 407th of 575 models in the data. MG as a brand averaged 80.9%, so this model runs 14 points behind its own brand.
A pass rate is not a reliability score. The full MGF MOT record has the pass rate by age, every common failure and how the MGF compares with similar cars.
MGF fuel types
Petrol was the most common fuel among MGF cars tested in 2025. Diesel made up just 0% of tests.
Where the MGF fails its MOT
Where MGF cars that failed their 2025 MOT were marked down, as a share of all recorded failure items.
The specific items testers recorded most often were rbt (sp) efficiency below requirements (5.4%), catalyst emissions carbon monoxide content after 2nd fast idle exceeds manufacturer's specified limits (5%) and component mounting prescribed areas prescribed area excessively corroded significantly reducing structural strength (3.5%). See every common MGF MOT failure.
These are DVSA failure records across every MGF that failed, not a claim that every MGF has these problems.
What should you check when buying a used MGF?
The areas above, most common first, and what an MOT tester looks at in each.
1
Brakes
Make sure the pedal feels firm, the car stops in a straight line, the handbrake holds on a slope and no brake warning light is showing. 20.8% of MGF failure items.
2
Lamps, reflectors and electrical equipment
Walk round with every light on: headlights, brake lights, indicators, fog lights and the number plate lamp. Check no warning lights stay on after starting. 19.4% of MGF failure items.
3
Noise, emissions and leaks
Listen for a blowing exhaust, watch for smoke on start-up and look under the car for oil or fluid leaks. 18.2% of MGF failure items.
4
Suspension
Listen for knocks over bumps, check the car sits level, and look for leaking shock absorbers and split rubber gaiters. 17.4% of MGF failure items.
5
Visibility
Check the windscreen for chips or cracks in the driver's view, and that the wipers and washers clear it properly. 8.4% of MGF failure items.
None of this replaces the car's own record. Run a free MOT history check on the registration to see every test, advisory and recorded mileage for that car.
What the MOT record doesn't tell you
Knowing MGF failures cluster around brakes and lamps, reflectors and electrical equipment tells you what to inspect. It tells you nothing about whether the car is safe to buy. An MOT does not show money still owed on the car, a write-off, a theft record or a clocked odometer.

Used MGF FAQs
Is the MGF reliable?
MOT data does not measure reliability. It records whether a car met the roadworthiness standard on the day of its test. What it does show is a 66.9% first-time pass rate for the MGF across 5,318 tests in 2025, below the 72.3% average for all cars.
What should I check before buying a used MGF?
On the car itself, start with the areas it most often fails on: brakes, lamps, reflectors and electrical equipment and noise, emissions and leaks. Then check the individual car's history: outstanding finance, insurance write-off records, stolen markers, mileage and previous keepers. None of these appear in the MOT record or on the V5C.
How do I check a MGF's history?
Enter the registration of the specific car. A Carpeep car history check reports outstanding finance, write-off category, stolen markers, mileage history, previous keepers, MOT and tax status, import and export markers and scrapped status in one £15 report.
MOT figures are aggregated from the DVSA MOT Anonymised data set for 2025 (class 4 initial tests, retests excluded), licensed under the Open Government Licence v3.0. MOT results describe roadworthiness at test, not mechanical reliability.
