The obvious pluses concerning this vehicle is the style, image, and the retracting hard top. The selling feature for me was the hard top convertible. This year's model has some minor improvements, the engine and its improved horse power and 0-60 speed put it in the running with the entry level Porsche. Unfortunately, I've driven both and the Porsche is still the better of the two. My 350 SLK is sexy in a girly kind of way. The Porsche is way more sport car than Mercedes is capable of building. I regret that I didn't spend more to get the car of my dreams. My wife's vote (and veto of the Porsche) cinched the deal and the SLK won the deal.

The seats are too small for a comfortable long distance drive.
