dammit, im late in this thread,
C210 sedan.
81 model were all injected, and for their age are quite nice to drive, they came with power steering aircon and power windows, the lucky ones also got power mirrors.
i have one of these which i picked up almost a year ago for 1600 dollars, registered. mine had bad paint though.
they are quite difficult to sell, but if your not in a hurry, it will sell eventually.
i currently have one for sale and also two coupes of the same model.
even though most people beat me to the punch, i hope this helped,
Jason
