The SL500 comes with a 5.0-liter V8 engine and a seven-speed automatic transmission and the ABC active suspension. It has more standard equipment than just about any other two-seater in the world today. It comes loaded with everything a driver and one passenger need for grand touring, from Bose stereo to beautiful interior decor. Traction control, electronic stability control, electronic brake distribution and brake assist all come standard. Passive safety features include frontal and side-impact head-and-thorax airbags as well as knee airbags. A rollover protection bar automatically snaps up if its controlling computer senses that the car is tipping over.The Mercedes-Benz SL-Class is a carryover from 2005.
