Considering the amount of C280's out there, I would pass and look for one in good mechanical order.
That engine could have been Overheated aswell sometime in it's life....That's what I figured, the interior alone would cover the expense. I may be trading my 78 300D for it if I don't just pay cash but we'll see. I have yet to do a compression test on this w202, I know it's going to be low but it's doubtful that it would be on all 6 cylinders unless the head bolts loosened up, the head warped or someone really beat this car to death. If there's excessive wear I'm walking away but if not I'm going for it.
For some reason all my tasteless friends don't like taking my old diesel out to the bar
