- National first-time pass rate, all cars and years: 77%
Every MG Zs model year
Pass rates fall as cars age, so the only fair comparison for a 2019 car is other cars of the same age. The full run for the MG Zs:
| Year | Pass rate | Tests | Avg mileage |
|---|---|---|---|
| 2002 | 65.4% | 211 | 92,903 |
| 2003 | 63.2% | 277 | 86,718 |
| 2004 | 68.9% | 354 | 91,265 |
| 2005 | 72.2% | 259 | 93,474 |
| 2017 | 76.6% | 350 | 45,629 |
| 2018 | 80.5% | 5,086 | 41,938 |
| 2019 | 83.3% | 8,016 | 34,559 |
| 2020 | 84.9% | 4,385 | 28,249 |
What this means if you are buying a 2019 Zs
The 2019 sits close to the MG Zs average, so there is no strong model-year signal either way. Judge the individual car on its own history. 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 7-year-old car fails on
A 2019 car is 7 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 below average for a car this age, worth a mileage-consistency check since an unusually low reading is sometimes clocking rather than luck. On a 2019 MG Zs the average at test was 34,559 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 2020 at 84.9%, and the weakest in our data is 2003 at 63.2%. That 21.7 point spread across the model's life is why comparing a 2019 car against a newer one tells you very little.
