These are an instant classic. This E550 uses Mercedes' M278 engine, which is a 4.7-liter twin turbo V8 which is rated at 402 HP and 443 TQ. It's also mated to a 7-speed automatic transmission that propels all four wheels. What all this adds up to is a very accommodating and comfortable sedan that will knock the doors off a lot of modern sportscars. While going quick is fun, it's really the experience and fit/finish that makes this car so appealing. Bluetooth audio, multiple LCD screens, fully adjustable heated/vented seats, and so much more make this car such a nice place to be. This car will make its next owner very happy.
