The same model, 3 years apart, compared on 134,222 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 134,222 tests, the 2019 Octavia passes 89.1% of MOTs and the 2016 87.1%. The 2019 cars are 3 years newer and were tested at a median 50,244 miles against 82,024, so part of that gap is simply age and use. Against what their age and mileage predict, the 2019 is −0.4 points and the 2016 +3.1 — a like-for-like gap of −3.5 points. Most of the raw advantage disappears once the two are matched. Typical repair bills are £35–£88 on the 2016 and £43–£107 on the 2019. The two bills are close. Repairs under £30 account for 26% of the 2016's recorded faults and 0% of the 2019's. Both years fail most often on windscreen.

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.
