FAQs

Is a 2001 Mercedes-Benz Clk reliable?

2001-registered examples passed 74.7% of their MOT tests (3,999 tests, 2023–2025), +8.1 points versus all UK cars registered in the same year. At roughly 25 years old with a median 99,251 miles, condition now varies car by car — always check the individual MOT history.

What mileage is too high for a 2001 Clk?

The median tested example shows 99,251 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.
