Since this is the 50th anniversary of the SL, there will be a limited run of 550 50th Edition SL550s, all with brown leather interior, pewter paint, and black ash wood trim, a handful of special options made standard, special trim and matching 50th Edition luggage.

The high-performance SL55 AMG ($128,800) features a supercharged 5.5-liter V8 and special tuning by AMG. The SL65 AMG ($186,000) is powered by a 6.0-liter twin-turbo V12, rated at 604 horsepower and a staggering 738 pound-feet of torque. Both AMG versions, in addition to their special front, rear, side, and interior trims, sport seats, and AMG alloy wheels, have a new dashboard information display that includes for the first time a RaceTimer feature that will track lap times, lap length, average speed, and top speed. The SL65 AMG gets an electric trunk closer, aluminum steering-wheel-mounted shift levers, a complete carbon fiber interior, and a center high-mount stop lamp in white instead of red.

The safety package leaves nothing out. All SL-Class models comes with ABS with huge disc brakes, ESP electronic stability control, traction control, ABC automatic body control suspension, front and side air bags, and an automatic deployable rollover hoop behind the seats.

Options include a comfort package, wood-and-leather trim package, AMG Sport package, hands-free communication package, bi-xenon headlamps, Distronic cruise control, Parktronic park assist, run-flat tires, the Keyless Go entry and starting system, and the Panorama roof option, all at about the same prices as the 2006 model.
