I've owned the SLK for a little over a year, and am very happy with it. I was initially attracted to the car because of its looks, styling, and impressive engineering. Supercharger provides enough of a boost for highway passing; otherwise, I would recommend a 320. Expectation met with just one exception.
Hardtop convertible, and a fun 2nd car on the way to an SL.
Cheap, tacky plastic interior. I still cannot understand why Mercedes would not offer leather as an option. The only way to rid unsightly scratches to the plastic console is to replace it with another cheap plastic console.
