Purchased a CPO E320 Bluetec with 24K miles. Impressed with build quality, drive ability, features. I'm 6'4, 220 lbs, and have plenty of leg, hip and headroom both as a driver and as a passenger (can sit comfortably behind driver's seat which was set to my specs). Took a 1K mile shakedown to NW PA and averaged about 35.5 mpg in mostly highway driving between 70 - 75 mph. Stone quiet, provides a great sense of confidence in ride and handling qualities. Only quibble is the COMMAND radio system, for its apparent sophistication, has no satellite radio standard. I do not miss nav - that's why I use AAA maps!
