2010 Mercedes-Benz E-Class E550 4dr Sedan (5.5L 8cyl 7A)
Traded a 2009 BMW 528xi after 4 months for this car. Even in non-sport models, BMW's are still race cars (I don't care what anyone says). They're louder, firmer and difficult to drive long distances with one hand. Gets a little tiring. Enter the E550. This is a true luxury car: quiet, smooth, very fast, rides like a dream. Put the suspension and transmission in sport mode and it'll take on any BMW. When you calm down again, flip it back to comfort mode and enjoy. Amazing! My wife gave the gas a good stab to pass another car and said she couldn't stop giggling for minutes afterward. This car is seriously fast!
Airmatic suspension, Driver Assist Package, Dynamic Driver Seat (thought it was silly until I had it...not laughing anymore). Very nice stereo, too! And, what are these?...Cup Holders?!?
Rain-sensing wipers are not that great. BMW definitely has that feature nailed.
