The SL is the iconic luxury convertible from Mercedes-Benz. With a lineage that dates back to the SSK and SSKL of the 1930's, SL models have been a consistent and visible part of the Mercedes brand. With power to spare, the retractable hardtop SL convertible is all about indulgence. Engine choices include V8 and V12 power. The AMG models offer straight-line performance that can only be exploited on a racetrack or the autobahn. The 2012 model year is the last for this body style.
