2002 Mercedes-Benz CLK-Class CLK320 2dr Coupe (3.2L 6cyl 5A)
I have owned my CLK 320 coupe for 3 years. The car is now at 39,000 miles. The car started out well when first purchased but is now falling apart. The engine valve rocker arms have been replaced 4 times and are still loud when the car is cold. The front seat track has been replaced as well as both rear seat latches as well as the outside temperature sensor and all of the instrument guages. The tires wore out at 14,000 miles and the ignition wires had to be replaced at 33,000 miles. The undercarriage is now making a loud rattling sound like marbles in a bucket.
Gas mileage averages 24 mpg combined city/highway. Highway mileage is as high as 33 mpg if driven in 45-55 mph range for prolonged periods.
No one can afford to own this car after the warranty expires due to the numerous mechanical failures. From what I have read the new Mercedes cars are not any better. Forget about Mercedes unreliability - buy a Lexus.
