This is an amazing automobile. With almost 500HP, a fast shifting transmission (with 3 ways to shift - full auto, tiptronic or steering wheel paddles) and excellent handling, the performance is truly outstanding. It's not as much fun to drive as my Porsche. It is, afterall, a sedan, but it's the best sedan I've ever driven. Despite the build quality problems that Mercedes has experienced in the recent past, none of it seems to pop up in the AMG cars. Perhaps the AMG cars get more TLC. The list of standard features is long and luxurious. One of the best is the drive dynamic seats. The side bolsters inflate/deflate in response to lateral G's. Great fun! Expensive, but worth it.
Drive dynamic seats. 3-ways to shift the transmission. Navigation. Air conditioned seats, memory seats. Steering wheel and mirrors, electric folding mirrors. Command system. Xenon headlights. The great AMG brakes.
Move CD changer from the trunk to the dash. Place line select keys on the navigation display. Larger gas tank.
