The SLK Class lacks in two things roadsters usually have in abundance: wind noise and poor rear visibility. This can be credited to the well-designed power-retractable hardtop works well, and is not fussy, and the head restraints have warm air vents that blow on the driver's and passenger's necks keeping them warm even when the roof is open. Handling is sporty and quick, and the interior is as comfy as the ride. The SLK300 and SLK350 get a respectable 26 mpg on the highway.
