Mercedes-Benz SLK

Many innovative features add up to a unique rear-wheel-drive roadster. An electrically retractable hardtop, which folds and stows itself in the trunk when it's lowered, makes this convertible feel almost as solid as a fixed-roof coupe. And a sensor deactivates the passenger-side air bag if you mount a specially designed child seat there. A supercharged, intercooled 2.3-liter, 185-hp Four provides the power. A manual transmission is available. A V6 is offered as well.
