Across 1,033 MOT tests, the Grafter N35.150 returns 71.3% first-time pass — below the UK fleet average. The single most-logged Major fail is windscreen damage.

Year-band analysis

Best year to buy. Worst to avoid.

First-time MOT pass rate split by registration band. A 14.1-point gap between bands means the year you buy Isuzu Trucks Grafter N35.150 has a real effect on what turns up at the garage.

Best band to buy

82.3%

2021+ registration

the 2021-on band climbs to 82.3% — a 14.1-point improvement. Tests in this band average 37,099 miles — roughly 79K miles fewer on the clock than the older band. Failures here are mostly wear items: inoperative in the case of multiple lamps…, 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

68.2%

Pre-2018 registration

On the older band (pre-2018), the data shows a 68.2% pass rate against a fleet average of 82.3% on the newer band. The main culprits logged at test: inoperative in the case of multiple lamps…, damaged but not adversely affecting driver's view, and not working. Average mileage on test for this band is 115,620 miles — high-mileage wear items are a recurring theme.

Best band to buy: 2021+ (82.3% first-time pass). Worst band to avoid: pre-2018 (68.2% pass). That's a 14.1-point spread across 1,095 older tests and 221 newer ones — year of build makes a material difference on this model.
