My second CLK Cabrio, traded a (trouble free) 2003. This car is a vast improvement over the already great former version. Beautiful to look at and fun to drive. Many great comfort features and trouble free at 2000 miles. Drove the 500, not worth the extra money, maybe the 550 will be better. iPod kit is awesome! MB has become more "Lexus-like" to compete, but the car is very refined. A little less plastic would be nice.
iPod kit. Styling, easy top. Sirius radio. Good cupholders (finally), seat- belt pretensioners.
More items standard for $60K+. Navigation, bluetooth, etc. Go back to power-glide seats, the "spring-forward" seats are cheesy for an expensive car! The spring-loaded trunk lid should come standard with an auto closer.
