Mercedes Benz Clk (2007)
2007 Mercedes Benz Clk
CarHunch analysed 5,616 real MOT records for the 2007 Mercedes Benz Clk. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2007 Mercedes-Benz CLK has a first-time pass rate of 76.6%, which trails the UK average by 3.4 percentage points and suggests middling reliability for its age. More worryingly, over half of these vehicles (51.2%) have recorded a dangerous defect at some point, making this a serious buyer concern that demands a thorough pre-purchase inspection.
These CLKs are running at a median mileage of 64,781 miles—reasonable for a 17-year-old car—but they're racking up an average of 4.43 failures and nearly 25 advisories per MOT test, pointing to widespread wear and costly electrical or suspension issues. Petrol versions perform slightly better at 77.6% pass rate versus 75% for diesels, so opt for petrol if you have the choice, and budget for regular remedial work before each test.
Petrol vs Diesel
Pass rate difference of 2.6 percentage points — worth knowing if you're choosing between the two.
What to check before buying a 2007 Mercedes Benz Clk
