Ordered in June after driving 2005 demo. 2006 arrived with no arm rest; roll top desk top instead. After 5 weeks, driven it only about 100 miles. When I go to use it I think "sore elbow," and use a different car. I have a C240 wagon and until recently a CL600. Both had a plastic runner at the bottom of the door opening. This one has fabric - great for attracting stains. Mercedes appears to consider its customers incompetent when it comes to lowering the back seats. An interlock moves the passenger seat forward, after which it might just accommodate a five- year-old. All kinds of hassle to overide this interlock so as to be able to use the seat. Wonderful vehicle spoiled by dumb design.
Acceleration and suspension.
Put the armrest back in, use material which can be easily cleaned at the lower door openings, don't patronize customers by automatically moving the passenger seat so far forward it becomes unuesable, make the third row seats optional so as to provide secure, covered storage when back seats are down.
