Across 802 MOT tests, the 2020 Toyota Supra Pro recorded a 93.6% pass rate. Against all cars of a similar age (9.3% fail rate), the 2020 Supra Pro comes out 3.0pp better. Failures cluster in tyres, emissions & environmental and other defects.
What the MOT record shows
Tyres dominates the failure mix at 5.0% of all tests — 4.0 points clear of emissions & environmental, so it is the first thing to check.
At component level the recurring items are tread depth, registration plates and catalyst emissions — tread depth alone was recorded 15 times.
Advisories point at the next bill rather than this one: tyres was flagged on 14.1% of tests without failing them.
The trend is improving — the fail rate fell from 9.3% in 2023 to 4.2% in 2025, as the worst-kept examples leave the fleet.

What to check before buying a 2020 Supra Pro
On a 2020 Supra Pro, tyres is what the MOT record says goes wrong most — it appeared in 5.0% of tests. Check these areas before you commit.
- Tyres (5.0% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
- Emissions & environmental (1.0% of tests): More common on older diesels (DPF/EGR) — can be expensive; check for warning lights and smoke. Typical repair: £100–£600.
- Other defects (0.9% of tests): Miscellaneous items not in the main categories. Typical repair: varies.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
