Year-band analysis
First-time MOT pass rate split by registration band. A 2.8-point gap between bands is modest — the year you buy Ford Transit Custom 320 Trend Eblue makes a small but real difference to MOT outcomes.
Best band to buy
77.2%
2021+ registration
the 2021-on band climbs to 77.2% — a 2.8-point improvement. Tests in this band average 48,431 miles — roughly 14K miles fewer on the clock than the older band. Failures here are mostly wear items: does not clear the windscreen effectively, blade defective — the structural issues that drag down older examples don't appear in the top-10 for this band.

Band to be cautious about
74.4%
2018–2020 registration

Average mileage on test for this band is 62,654 miles — high-mileage wear items are a recurring theme.
