After 200,000 trouble-free miles, my 300E was totaled in a 50 mph rear-end strike by a Chevy SUV. All four doors still open perfectly despite the car being crushed up to the rear window.As an engineer I understood the strength of this body, so I bought another 1993 300E 3.2 to drive for another 17 years. A wonderful solid car, albeit not flashy, just excellent.
The seats are exceptionally comfortable for long drives, and the car is reliable if you have regular scheduled maintenance.It is exceptionally stable at high freeway speeds and beyond. A real MB sleeper.
None, the car is a driver, not a rolling entertainment center. No cup holders, no frills. I drove mine at 100+mph in AZ all the time. It was stable at those speeds. It'll move 4 people comfortably and still get 25 MPG.
