My 2007 Benz CLK 350 has been an awesome car! Very dependable and reliable! No complaints here! Well, maybe wish it had a bigger back seat....then I guess I should have bought a 4 door sedan then! No! I am very happy and highly recommend the CLK! I have seen many negative remarks about this car but if you research all cars no matter the brand you will find flaws and defects with all makes and models including the BMW brand etc. Also, the Mercedes is so much cheaper to maintain than the Beamer, I know first hand experience! :) on this one!
My experience is only 1 month old, but if my initial response is any indication of the future, this is one fantastic vehicle. I have owned over 80 cars in a lifetime of ownership from BMW and Jag to Corvettes, Porsche etc.. My CLK 550 is one of, if not the best of the bunch out of the box! Very fast and very smooth. Handles incredibly well under all but ice and snow for which I have no experience whatsoever. It will stay in the garage for sure during these periods! Fit and finish is everything one can expect from a $60K vehicle.
Bought a certified CLK550 Coupe with all the options a few months ago. Absolutely love the car, great power, decent handling and nice interior. Came from an 01 Corvette and the CLK550 is every bit its equal in power. Handling is a little on the softer side but much easier to live with every day. Drove '06 M3 and '08 335 before choosing the CLK. Basically went on features and power the BMW's could hold up. 335 might have a little more speed here at altitude (CO - 6000') due to the turbos; but overall like the CLK much better and am very happy with my choice.
Recently purchased a certified pre owned (cpo) 2007 CLK350 Coupe; gem of a car but since found out it has one EXPENSIVE FLAW ! Various Mercedes Benz models built between 2005 and 2008 have a defective balance shaft and/or balance shaft sprocket. It's a defect in the metal part which wears prematurely. To replace and repair, it in the CLK models with the 350 (272) engine, it requires removal of the engine!! The dealer knew this problem exists and didn't tell me before I made the purchase. I bought this car in good faith that it would last me many years, now I found out it will likely need an engine tear-down before it hits 100K miles, maybe closer to 60K. Shameful.
Bought the car with what I think to be the standard exterior styling package which makes the car look like an AMG tuned sports car (with AMG rims etc). Has beautiful Cappuccino Brown/Black Leather-Sport leather seating with an amazing leather interior. More comfortable interior than any coupe in its class. Test drove new 3-series coupe but fell in love with the powerful CLK. with 3500 miles, still have fun and remain comfortable driving the car. Must get Xeon lights and ventilated multi-contour seats for maximum comfort.
