The 2008 Mercedes-Benz CL passes its MOT first time at 84.7%, which is above the UK average of 80%, but a significant concern emerges in the dangerous defect rate: 35.9% of these cars have recorded at least one dangerous fault, well above acceptable levels for a buyer considering one. This suggests underlying structural or safety system issues that warrant thorough pre-purchase inspection.

These cars are running at a modest 58,148 miles median, which is reasonable for their age, yet they're still averaging 2.07 failures and 13.7 advisories per test. The high advisory count points to cumulative wear on electrical, suspension, and comfort systems typical of ageing luxury cars. Before committing, insist on a full independent inspection focusing on brake systems, suspension geometry, and electrical integrity—don't rely on the MOT pass alone.

We have limited data for the 2008 Mercedes Benz Cl — treat the figures below as indicative rather than definitive.

⚠️ Over 1 in 5 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.

Front Brake pad(s) wearing thin · Offside Front Brake pipe corroded, covered in grease or other material · Front Brake disc worn, pitted or scored, but not seriously weakened · …
Ask the seller when brakes were last serviced. If they don't know, factor in the cost.
Suspension & steering 20.7%
Offside Front Wheel bearing has slight play · Nearside Front Wheel bearing has slight play
Harder to spot without a ramp — this is a good reason to book a pre-purchase inspection.
