mine's a 1973 coupe... has 54000 miles on the odometer, I presume it has been around once. I have replaced most of the running gear since I have had it, just the diff to go (it's getting pretty noisy).

Previously my family had a 120Y sedan that did 300000km on the original running gear. Over all those miles, the only thing replaced was the valve stem seals at one point to solve a slight oil burning problem. It was still running fine when the 300000 clicked over, but my parents felt sorry for it and pensioned it off.
