 If you get a CLK550 Cabriolet, the sport suspension option is a must have. Had mine trucked down to N. Cal. from Wash. State, since it was only one in Western USA with sport suspension (for me), run flats (for wife), backseat side airbags (for son), and P3 option (best front seats).  It has every opt. except power trunk closer. This is the best Mercedes I've every owned, and been loyal customer since bought 380 SL in 1982! Solid build, no problems, performs better than last year's AMG model for $20K less, quiet with the top up. 0-60 mph on mine is much faster than 5.1 sec. spec. It can go 65+ on 25mph curved exit w/o ESC.  Wish I could take it to Germany and drive it on the Autobahn!
