With a rich history dating to the mid-1950s, the Mercedes-Benz SL is the automaker’s flagship grand touring car, equipped with seating for 2 people and a power-retractable hardtop that transforms it from a coupe into a convertible. Turbocharged engines include V-6, V-8, and V-12 configurations, and the SL is available in two different states of AMG performance tuning in addition to SL450 and SL550 model series.
