After driving an 06 SL55 AMG I traded my fully optioned and modified 04 CLK55 AMG for this fully optioned car with the 030 Performance Package. I had it less than a month when it was totaled on 12/31/08. I am so impressed by this car I bought an 07 SL55 AMG with the 030 and all options after the insurance claims were settled. For comparison I tested the 09 Shelby GT500KR, 09 Chev Corvette Z06, 07 BMW 650i convt, 08 BMW 550 Sport and an 08 SL550 Sport. I even considered an 08 CLK63 Black Series. Personally, I think the SLs are great cars that can do everything very well. Although it is not as nimble as my previous 03 BMW M5 and 02 M3 its still my 1st choice. It's stablemate is a great 05 E55.
Everything and did I mention 510 HP, 531 foot pounds of torque mated to the 030 Performance Package? Wow, what a car!
