Sorry to say I can't agree with most of the E350-4M reviews. It has been back to the dealer 10 times mostly for electrical problems (oil level message, ESP/cruise failure but also incl 2 recalls). Nice ride, good fuel mi (27 hwy) and good performance but the reliability has been a nightmare. This was always my "one day I'll have a MB" - didn't do my normal comparison testing and am paying for it. If you want further quantification just check out the resale - dropped from $57k new to $37k in 14 mos!!
