Inside, the added length and width have created passenger quarters that are a tad more roomy. The environs remain cozy but less cramped. Still, storage is almost non-existent but for the glovebox and door pockets. Purses, briefcases and jackets have to stow in the trunk when two passengers are aboard. Highly adjustable in a variety of directions, the seats are extremely comfortable and supportive even during long drives.What's most impressive about the new SLK interior is the giant leap in quality of materials. The material covering the dash is irresistible to touch, soft and almost silky. Switches, buttons and trim are silver against the dark background. Five color choices for the interior are offered, black, blue, beige, red and ash. The ambiance is high-tech but not in a steely cold way, but rather in an inviting manner. The only wood is that which is ordered with the optional Vavona wood trim package.
A large center console divides the cabin in half. The console is home to the optional navigation and communications systems. In front of the driver, the redesigned instrument cluster features two large dials surrounded in silver, one of the speedometer, clock and fuel gauge, the other for the tachometer. Both have white needles.
