Traded 2009 Porsche 911 Cab PDK on this. 911 great but rough ride and hard egress/exit. Mercedes is a great all around car. If you really aren't ever going on a track, this is the perfect car. Very torquey V8, brisk in normal or sport mode. Tip-in and shifting very aggressive in sport mode. A quality car with great electronics. I have 1400 songs on 1 8.5 Gig DVD, Player will take 5 more!! Transmission is not as good as Porsche PDK, but way more than you need for aggressive road driving. Exhaust note is a pleasure. I think Mercedes gets it, and I'm glad I got it!
Power, looks, handling, sound, top down, room for 2 (shorties) in back.
Could be 3-4 inches bigger in back seat. No route list available in Nav, a major deficiency, unless you really don't care where Nav takes you.
