2000 SEAT Leon — MOT failures & pass rate
581 MOT tests on the 2000 SEAT Leon are in this dataset, and 72.5% of them passed. Small family cars of a similar age fail at 27.7%, so the 2000 Leon sits squarely on the average. Failures cluster in lighting & signalling, suspension and brakes.
What the MOT record shows
Lighting & signalling dominates the failure mix at 15.2% of all tests — 4.3 points clear of suspension, so it is the first thing to check.
At component level the recurring items are catalyst emissions, pins and bushes and stop lamp — catalyst emissions alone was recorded 66 times.
Mileage is the strongest signal on the record: 18.2% of 30-60k cars fail, rising to 33.6% once past 150k.
Advisories point at the next bill rather than this one: brakes was flagged on 39.2% of tests without failing them.

What to check before buying a 2000 Leon
On a 2000 Leon, lighting & signalling is what the MOT record says goes wrong most — it appeared in 15.2% of tests. Check these areas before you commit.
- Lighting & signalling (15.2% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (10.8% of tests): Worn drop links, bushes, springs or shocks — listen for knocks over bumps and check for uneven tyre wear. Typical repair: £150–£450 per corner.
- Brakes (9.3% of tests): Pads/discs are routine wear; binding, imbalance or corroded pipes are more serious — test for pulling under braking. Typical repair: £100–£350 per axle.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
