SEAT Leon years to avoid — 500,111 MOT tests ranked
Every Leon year, ranked
The age-adjusted MOT index sets 100 as the pass rate of all UK cars registered in the same year and tested in the same calendar year. Higher is better. This prevents an old car being labelled a “bad year” simply because it is old.

Why 2018 and 2019 and 2020 rank lower
The 2018 cohort passes 84.5% of tests (-1.9 points versus same-age cars) at a median 49,060 miles, with tyres the leading failure system. The 2020 cohort passes 87.2% of tests (-2.7 points versus same-age cars) at a median 32,804 miles, with tyres the leading failure system. The 2019 cohort passes 84.4% of tests (-4.0 points versus same-age cars) at a median 40,082 miles, with suspension the leading failure system. This is population-level evidence, not a known-fault list: service history, engine version and the individual MOT record can outweigh the registration-year average.
How to use this before buying
- Rankings describe the cohort, not the car. A cherished 2018 example beats a neglected 2003 one — always run the specific reg through the free MOT history check.
- Read the advisories. Repeated notes for the same component across years mean the owner has been ignoring it. Decode them in our advisory library.
- Scan before you pay. A 2-minute OBD scan reveals stored faults the dashboard hides — see our scanner guide.
FAQs
Which Leon years should I avoid?
Based on 500,111 MOT tests adjusted against cars of the same age, 2018, 2019, 2020 are the lower-scoring outliers. That is a prompt for closer inspection, not proof that every car from those years is bad.
What is the best Leon year to buy used?
2003 and 2014 lead the age-adjusted MOT ranking. The score compares each registration year with all UK cars of the same age; the specific car's history and condition still take priority.
Is the Leon reliable overall?
Across 500,111 tests, the median age-adjusted index is 101.9 (100 equals the pass rate of all cars registered in the same year). Use the spread between years as one signal, then check the individual registration.
Methodology: index = 100 + the model-year cohort’s MOT pass-rate difference versus all UK vehicles registered in the same year and tested in the same calendar year. Class 4 initial tests only; retests excluded; at least 1,500 tests per page. “Inspect” years are below both the same-age baseline and the model’s median index by at least 2 points. Association is not proof of a model-year defect. DVSA anonymised data 2023–2025, OGL v3.0.
