For the brand’s die-hard fans, the SL-Class continues to be the Mercedes-Benz “object of desire par excellence.” This superb GT (Gran Turismo) is available as a coupe or convertible, both of which are seductive enough to cause a stir wherever they go. There’s the “tame” SL550 and its 382 horses, then there’s the devilish SL63 AMG and its 518 broncos. No more V12s, just efficient V8s!
