I just took delivery of a CPO 2007 E350 4Matic and love it. Have owned BMW and Audi in the past, but always wanted to own the Gold Standard. Power is surprisingly good for a 3.5 L engine, interior and exterior quality are outstanding. All I can say is there is a reason everybody wants to own a Mercedes. Best decision I've made in a long, long. time.
Interior/exterior styling, engine power and quietness, overall chassis stiffness and quiet, interior comfort, outstanding wiper system, sporty but refined handling.
Separate cruise stalk, jerky electrically adjustable O/S rear view mirrors, Needless "manual" shift control feature, tiny glove box, dual hood ornaments (stand-up star and surface-mounted badge are overkill on an otherwise extremely tastefully executed car).
