Dad had an '83 300 TD sedan, man what build quality, this must have been the car in mind for whoever coined the quip, "machined out of a block of steel." Once got into an accident where he was rear ended hard enough to knock the motor off its mounts and pushed into the car in front. Both other cars were nearly totalled while my dad drove away to his mechanic to fix a tail light, re-extend the rear bumper and put that lump of a motor back on its mounts. Simply incredible, back in the day when Mercedes were built to the Nth degree of engineering rather than the fancy, mega power gadget machines of today.
I'd love to pick up some clean, low mileage (<200K) 300 TD wagen, should be nearly broken in at that point.
