Toyota YARIS 2015 vs 2019
The same model, 4 years apart, compared on 190,693 real MOT tests. The raw pass rate mostly measures age; the like-for-like row and the mileage bands show what survives that adjustment.

The short answer
The 2019 YARIS passes more — but most of it is age
Across 190,693 tests, the 2019 YARIS passes 92.7% of MOTs and the 2015 88.1%. The 2019 cars are 4 years newer and were tested at a median 25,960 miles against 51,906, so part of that gap is simply age and use. Against what their age and mileage predict, the 2019 is +3.2 points and the 2015 +6.0 — a like-for-like gap of −2.8 points. Most of the raw advantage disappears once the two are matched. Typical repair bills are £20–£53 on the 2015 and £20–£50 on the 2019. The two bills are close. Repairs under £30 account for 72% of the 2015's recorded faults and 63% of the 2019's. The most common failing part is number plate lamp on the 2015 and wiper blade on the 2019.

Does the gap hold at higher mileage?
Pass rate by the mileage recorded at test. If the lead shrinks in the high-mileage bands, part of the headline difference was a younger, lower-mileage sample.
