The same model, 4 years apart, compared on 479,724 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
Across 479,724 tests, the 2019 Corsa passes 87.2% of MOTs and the 2015 77.7%. The 2019 cars are 4 years newer and were tested at a median 29,970 miles against 60,189, so part of that gap is simply age and use. Against what their age and mileage predict, the 2019 is −2.3 points and the 2015 −4.4 — a like-for-like gap of +2.1 points. Most of the raw advantage disappears once the two are matched. Typical repair bills are £21–£52 on the 2015 and £16–£41 on the 2019. The older year is the more expensive of the two when it fails. Repairs under £30 account for 18% of the 2015's recorded faults and 61% of the 2019's. The most common failing part is ball joint on the 2015 and wiper blade on the 2019.

A ✓ marks the stronger figure in each row. It compares the two model years, not either one against the national average.
The most common priced failures on each year, as a share of that year's tests. Repair costs are estimates from UK parts data, not quotes.
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.
