CLK enjoyed for power, luxury, looks
Earlier models in this generation may have suffered from a coolant leak into the transmission, which can cause damage or even failure. Ask the seller of an earlier CLK if they’re aware of this problem, or if any work was ever performed to correct it on their vehicle. A Mercedes-Benz technician should be familiar with the problem and able to check for warning signs. This problem was eliminated by about the 2004 model year.

Check under the hood, and under the car, for signs of oil leaks, too. Be sure the third brake-light housing isn’t cracked or showing signs of internal moisture, and note any rough or ‘clumsy’ shifting from the transmission. This is likely a software-related problem, and a reprogramming of the transmission computer may be the answer.

Finally, some owners report poor paint quality, so be sure to inspect the paint job on the CLK you’re considering and call it into pricing negotiations should it not be up to par.

The Verdict Of A Used Mercedes-Benz CLK-Class: The CLK seems to be well-loved for its driving experience, performance and luxury—and it exhibits minimal worrisome problems. This won’t be a cheap car to insure and maintain, though a dealer-certified used model with no signs of trouble should be a reliable and enjoyable cruiser for the long haul.
