2003 Mercedes-Benz SL55 AMG (R230)

The R230 SL55 AMG (2002-2008) was AMG's supercharged super-roadster. The M113K 5.4-litre supercharged V8 produced 493hp, propelling the heavy SL to 60mph in 4.5 seconds. The combination of retractable hardtop practicality and devastating performance created a true grand touring convertible. The SL55 AMG offers excellent value as a used performance car.
