I use this car as a daily driver. Actually, since I bought the 93 190E, my wife has been driving the C280. (She doesn't like to drive manual trannys)
I bought the W210 mirrors from MBenzNL who posted his pic above. I believe he sellls them for around $325 with W202 connectors.
My W202 is a 1994, so it uses the carryover shift knob from the 190E. I could have bought an adapter and put on a new style knob but I'm happy with the W201 Wood Shifter.
The trim was painted to match when the mirrors were painted.
