2011 Mercedes-Benz E-Class E350 4dr Sedan (3.5L 6cyl 7A)
Ex-BMW owner here. Since day 1. Wind noise at right rear window. Dealership had it for a week and couldn't figure it out. Really. Maybe isolated to just my vehicle, but very frustrating nevertheless! Great looking car, fantastic lines. Tons of comments from random people. Great interior and interior lighting. Decent if a bit bland on the driving attributes. Light but responsive steering. Inexplicable road hum from tires. Smooth hwy ride, substantial feeling, but at low speeds, occasional trouble finding right gear and can feel it. A few unacceptable and irritating squeaks and rattles already. Only have 1100 miles on the darn thing!
Sound system (with a bit of rear-deck rattle at volume), Bluetooth telephone, voice commands(though somewhat quirky), nice ride, full of features, great night-time ambient interior lighting. A very handsome looker of a car!
Better trunk lighting, re-position turn signal, cruise control and wiper stick.
