things I appreciate in my car:
* ABS
* heated mirrors, which prove their worth when there is freezing rain.
* MBTex upholstery
* full instrumentation
* brake lamps that are separate from the rear lamps, which makes braking more discernible from the rear
* the plastic lower-body cladding

things I would like to see in my car
* driving lamps, like those in the 500E/E500 (mine is a W201)
* rear fog lamp (it has been neutered in my model year)
* cupholders
