The Mercedes SLK improves with every new version. Post-2008 facelift SLK 350 is the perfect reason why you shouldn't spend more money on an AMG version. We like: lots of positive feedback from satisfied SLK 350 drivers, detailing reliability and decent fuel economy. Sharper steering courtesy of later variable-ratio rack. We don't like: A well-maintained facelift SLK 350 won't shame the owner while chasing hairy-chested supercars up mountain passes, nor will it spill the drinks.
