| The slk comes in one body style: A two-seat roadster with a power-retractable hardtop, in two versions: Slk280 and slk350. Standard equipment on the slk280 includes 16-inch alloy wheels, leather upholstery, sport seats, a tilt/telescoping steering wheel, dual-zone climate control and a nine-speaker CD audio system. In addition to a larger engine, the slk350 adds 17-inch wheels. Should this not be enough, there are many options to consider, such as a sport package with a lowered suspension, bi-xenon headlamps, a navigation system, a 380-watt surround-sound audio system, a glovebox-mounted CD changer, satellite radio, power-adjustable memory seats, seat heaters and an airscarf system that directs heat through vents in the head restraints. |
