 Bought a '07 CPO E350 Sport/ Premium 1, Blk/Blk with 21,000 miles for $31k Aug 09.  The car is very solid and well-built - no chassis flex, creaks, or rattles, very stable (runs likes it's on railroad tracks - smooth, stable and tracks very straight even at high speeds).  Great value for a car with an MSRP of $55k. Acceptable performance; but it's no rocket or track-day thrill ride. I also own a '06 BMW 330 w/ sport package - the E350 can't match the 330 in terms of performance but it is certainly a very comfortable, solid, spacious, safe and prestigious (if that sort of thing matters to you)car. Very happy with the purchase, a top-of-the-line Accord will run you about the same money!
