The two-seat 2009 Mercedes SL roadster rides the line between high-performance and ultra-luxury. The V12 SL600 is especially exclusive, while the AMG versions are tuned to be the ultimate luxury performance cars. The top SL65 AMG model is nearly twice the price of the SL550, but offers performance that can beat some exotic nameplates. Any of the models can be equipped with some extraordinary high-tech features, such as Dynamic Multicontour seats. These seats use air pockets to actively mold the seat to the driver's body.
