The picture
Across 766 MOT tests, the Transit Custom 320 Sport Eblue returns 86.8% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is windscreen damage. Wipers that don't clear the screen and a split CV-joint boot round out the top three. Average tested mileage sits at 41,131, which is the lens to read those failure rankings through. If you own one and the next test is close, the ranked list below is a sensible pre-test checklist.

Year-band analysis
First-time MOT pass rate split by registration band. A 1.7-point gap between bands is modest — the year you buy Ford Transit Custom 320 Sport Eblue makes a small but real difference to MOT outcomes.
Best band to buy
87.8%
2021+ registration
the 2021-on band climbs to 87.8% — a 1.7-point improvement. Tests in this band average 40,332 miles — roughly 15K miles fewer on the clock than the older band. Failures here are mostly wear items: damaged but not adversely affecting driver's view, constant velocity boot severely deteriorated — 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
86.1%
2018–2020 registration
On the 2018–2020 band, the data shows a 86.1% pass rate against a fleet average of 87.8% on the newer band. The main culprits logged at test: damaged but not adversely affecting driver's view, constant velocity boot severely deteriorated, and inoperative in the case of multiple lamps…. Average mileage on test for this band is 54,836 miles — high-mileage wear items are a recurring theme.
Best band to buy: 2021+ (87.8% first-time pass). Worst band to avoid: 2018-2020 (86.1% pass). That's a 1.7-point spread across 1,474 older tests and 912 newer ones — year of build makes a material difference on this model.
