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!
Engine, Acceleration, Sport Suspension, 7-speed with paddle shifters, Brakes, Keyless Go, Harmon Kardon, Steering wheel controls. Beautiful car in black metallic with black ragtop and black leather. Hearing Howard Stern again on the Sirius satellite radio!
Treo 700wx phone works with bluetooth but you can't upload the address book. Sirius radio tuner seems slow, and easy to lose reception even under tree cover. Glovebox should be lockable. Cupholder(s) in the back seat and parking sensors that detect the curb would be nice to have cuz bumper is low.
