Best band to buy
93.6%
2021+ registration
the 2021-on band climbs to 93.6% — a 1.5-point improvement. Tests in this band average 24,780 miles — roughly 5K miles fewer on the clock than the older band. Failures here are mostly wear items: has a cut in excess of the…, tread depth below requirements of 1.6mm — the structural issues that drag down older examples don't appear in the top-10 for this band. Post-2020 examples are early in their MOT life and generally show the cleanest records.
Band to be cautious about
92.1%
2018–2020 registration
On the 2018–2020 band, the data shows a 92.1% pass rate against a fleet average of 93.6% on the newer band.

Average mileage on test for this band is 30,004 miles — high-mileage wear items are a recurring theme.
Best band to buy: 2021+ (93.6% first-time pass). Worst band to avoid: 2018-2020 (92.1% pass). That's a 1.5-point spread across 984 older tests and 406 newer ones — year of build makes a material difference on this model.
