This sleek 12k-mile 2009 Mercedes-Benz SL600, originally delivered to Keenan Motors LTD in Doylestown, Pennsylvania, is a stunning example of German engineering and craftsmanship. Clad in Steel Grey Metallic with a black leather interior, this convertible beauty is powered by a twin-turbocharged 5.5-liter V12 engine mated to a smooth-shifting five-speed automatic transmission. With most of its life spent in the care of its original owner and currently located in Douglassville, Pennsylvania, this vehicle offers a rare opportunity to own a piece of luxurious motoring history with fewer than 12,000 miles logged on the clock.
