I was skeptical to buy a Mercedes, and felt it may be over priced, but it has been worth the money. Compared to other high end manufacturers, Mercedes drivers recieve the best overall performance and feel of a luxury car.
The sport version has so much room, I forget its kick other than the drive.
I would add toggle to the steering wheel for navigation like the radio feature.
Three major problems resulting in overnite service: Emergency brake release came completely out of dashboard; could not move vehicle. Harness for seatbags defective and had to be replaced. Starter key went "dead" after 17,000 mi. Could not reset clock for daylight time, nor could three dealer service personnel! Confusing option "sets" on steering wheel. etc etc
Remove significant number of items which are superflous to performance and are computer operated! My l998 E320 was perfect! Wish I had not turned it in!
We decided we needed seating for 6-7, but didn't want an SUV. That left the E series and the Volvo V70. The E350 is beautiful, well-appointed and comfortable/luxurious. The suspension and steering, however, are softer than they should be, especially if you are used to driving a BMW with sports suspension (or even an Audi). The Volvo V70 R was sportier in power and handling, and had WAY better front seats (the most comfortable seats I have ever sat in, in fact), but was too stark/dark in the cockpit. Probably, upgrading to the E55 Wagon solves the problem, but for $35k more, that's insane. Come on Mercedes, make it handle more like a German driving machine!
Rear facing third row seat and automatic power liftgate.
Tighter steering, better road feel and stiffer suspension.
