My wife loves her '95 C220, which we bought last December upon the demise of our beloved 300D. It had 42K on the clock then and just went over 50K. It is used mainly for her commute to DC and gets 20+ MPG.
We have had zero problems with it since getting the ABS straightened out under the Starmark warranty.
My only complaint is that the engine is not very smooth - "buzzy" is how I would describe it. It has a quick first gear and a less than gentle shift. It also needs about 3300 RPM for 70 mph, so that is a bit loud.
Fit and finish are first-class, if a little plain.
