Year-band analysis
First-time MOT pass rate split by registration band. A 1.4-point gap between bands is modest — the year you buy Renault Trafic Sl28 Sport Energy Dci makes a small but real difference to MOT outcomes.
Best band to buy
84.6%
2021+ registration
the 2021-on band climbs to 84.6% — a 1.4-point improvement. Tests in this band average 47,714 miles — roughly 13K miles fewer on the clock than the older band. Failures here are mostly wear items: damaged but not adversely affecting driver's view, less than 1.5 mm thick — 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
83.2%
2018–2020 registration
On the 2018–2020 band, the data shows a 83.2% pass rate against a fleet average of 84.6% on the newer band. The main culprits logged at test: damaged but not adversely affecting driver's view, less than 1.5 mm thick, and ball joint excessively worn. Average mileage on test for this band is 60,285 miles — high-mileage wear items are a recurring theme.
Best band to buy: 2021+ (84.6% first-time pass). Worst band to avoid: 2018-2020 (83.2% pass). That's a 1.4-point spread across 3,053 older tests and 2,605 newer ones — year of build makes a material difference on this model.
