FAQs
Is a 2006 Toyota Corolla reliable?
2006-registered examples passed 72.7% of their MOT tests (37,509 tests, 2023–2025), +8.3 points versus all UK cars registered in the same year. At roughly 20 years old with a median 100,514 miles, condition now varies car by car — always check the individual MOT history.
What mileage is too high for a 2006 Corolla?
The median tested example shows 100,514 miles. Anything far beyond that isn't automatically bad — a motorway-mile car with consistent service records often beats a low-mileage school-run car — but price accordingly and scrutinise the mileage trail for gaps or drops.
Should I buy the petrol or diesel 2006 Corolla?
In this cohort petrols pass 73.5% of tests against 68.6% for diesels. Mileage and use can explain part of that gap, so treat it as a reason to inspect DPF and emissions history, not a fuel-type verdict.
