The 1997 Mercedes-Benz CL passes its MOT just 74.7% of the time, notably below the UK average of 80%, and nearly three in ten examples have recorded dangerous defects—a significant concern for a buyer. This isn't a reliability problem that creeps up; it's a pattern, and one you need to account for in your purchase decision.

These cars are running 100,000+ miles on average for their age, which explains some wear, but the real issue is the frequency of failures: 3.28 per vehicle on average, with 16.6 advisories suggesting multiple minor issues accumulating. Before buying, have a pre-purchase inspection done by a Mercedes specialist and budget for imminent repairs, especially suspension and brake work—don't assume you're just buying a classic; you're buying a 27-year-old luxury car that's showing its age.
