This 2005 Mercedes-Benz SL 55 AMG is the supercharged flagship of the R230-generation SL, finished in silver over an exceptionally clean dark gray interior. It shows 66,800 miles and comes with a documented ownership history dating back to 2018, including Pennsylvania state inspection records and routine maintenance paperwork covering the current owner's full tenure with the car.
Power comes from AMG's supercharged 5.4-liter V8, rated from the factory at 493 horsepower at 6,100 rpm and 516 lb-ft of torque, paired with a 5-speed automatic offering a manual shift mode. This was one of the last Mercedes-AMG applications of the supercharged big-displacement V8 before the marque moved to the naturally aspirated 6.2-liter "63" engines that followed shortly after, making the SL 55 a distinct chapter in AMG's history: forced induction and old-school displacement rather than high-revving naturally aspirated character or turbo lag.
The R230 SL also introduced Mercedes' power-retractable hardtop to the model line in place of a traditional soft top, and on this car it operates as intended. Ride and handling are managed by Active Body Control, an electronically controlled adaptive suspension that was central to the SL 55's reputation as a genuine grand tourer rather than just a quick roadster. The trunk retains its factory multi-CD changer.
For a buyer looking for early-2000s AMG performance backed by real documentation rather than just a clean CarFax, this SL 55 offers a well-kept example of one of the more capable factory performance flagships of its era, with seven years of consistent maintenance records from a single owner.
