Every MG 3 model year
Pass rates fall as cars age, so the only fair comparison for a 2014 car is other cars of the same age. The full run for the MG 3:
| Year | Pass rate | Tests | Avg mileage |
|---|---|---|---|
| 2014 | 74.3% | 1,557 | 57,053 |
| 2015 | 74.2% | 2,352 | 52,350 |
| 2016 | 77.5% | 3,074 | 48,102 |
| 2017 | 77.2% | 2,885 | 43,584 |
| 2018 | 81.8% | 2,588 | 36,436 |
| 2019 | 85.7% | 3,678 | 29,179 |
| 2020 | 87.4% | 1,732 | 23,525 |
| 2021 | 90.9% | 738 | 19,755 |
What this means if you are buying a 2014 3
The 2014 is a weaker year for this model, passing 6.2 points less often than the MG 3 average. Some of that is simply age, so compare it against the 2014 figure for all cars above rather than against newer examples. Check the exact car with the free MOT history checker before you buy, and run its VIN and mileage through our free VIN decoder and clocking check.
What a 12-year-old car fails on
A 2014 car is 12 years old now, and age drives the failure mix more than the badge does. Across all cars tested, these are the categories that actually cause failures:
- Lights and electrical: 10.36% of all cars tested
- Suspension: 8.65% of all cars tested
- Tyres: 6.23% of all cars tested
- Brakes: 6.1% of all cars tested
- Visibility: wipers, washers, glass: 4.65% of all cars tested
- Body, chassis and structure: 3.18% of all cars tested
That is around average, so condition and service history will tell you more than the odometer does. On a 2014 MG 3 the average at test was 57,053 miles, so treat anything far above that as a car that has worked harder than its peers, and anything far below as one worth checking for the faults that come from standing still.
The strongest year for this model is 2021 at 90.9%, and the weakest in our data is 2015 at 74.2%. That 16.7 point spread across the model's life is why comparing a 2014 car against a newer one tells you very little.
