Purchased Dec'06 about 17000 miles so far. Only 2 issues, battery died first month, and heated seats didn't work even though cooled function worked, both fixed without further incident. The interior is user friendly and car-like, exudes luxury, huge improvement over previous generation. Very comfy seats. AC strong and cold in 100+ temps. 11mpg mixed 19mpg highway. My particular truck doesn't suffer the excessive wind noise but did notice it on the loaner. Changing from a CLK55AMG overall pleased with the vehicle. No vehicle is perfect, everyone has different needs. For overall combination of size, power, handling, luxury and utility, this is currently the segment leader.
