In the world of premium and exotic roadsters, only a handful of vehicles offer the exclusivity, performance and overall reliability of the 2009 Mercedes-Benz SL. Highlighting its stunning exterior is a clever retractable hardtop, allowing the SL to serve as both coupe and convertible. The SL's varied model line delivers performance ranging from impressively quick to awesomely fast, and the car's extensive list of safety features is unsurpassed in this category. Few exotics can match the SL's impressively smooth and comfortable ride, either. Price may be the SL's only Achilles' heel, with the lowest-priced SL starting tens of thousands of dollars higher than a BMW 650i or Jaguar XK.
