This was my second MB (C320 first), after owning 4 BMWs (740, 328, M3, 325), 1 Lexus (GS), and a RRover. I've always loved BMWs because they are fun to drive, but this MB has the cornering, performance and stability I loved in my BMWs plus the gorgeous design, interior comfort and luxury that BMW has been sorely lacking. The car is spacious, both in length and width. The commands are well positioned (seat adjust. on doors) and there are plenty of compartments. Fuel efficiency is fairly superior to an engine of its size. As a woman driver, this car provides m invaluable safety peace of mind; if breakdown occurs, unlimited roadside assistance is a push of a button away.
4Matic is flawless in NE snow storms, agile performance w/ superb stability, luxurious interior, TelAid (they have remotely opened the car for me twice), Nav, rear window screen, backseat comfort, leg room (husband is 6'3"), SOS and roadside assistance button and other safety features.
Adjustable driver's seat headrest (stuck on upward position), better factory installed windshield wipers (had to replace them, just as w/ C320), improved lumbar support, fold down rear seats should be standard, shld be maintenance free during warranty period.
