I love that it has survived intact all those decades with the original owner and a known history. Too bad about the original engine getting damaged due to overheating & the drain plug being jettisoned. At least the documentation is still with the car.
A Teal Blue Custom Coupe with Z03, Z24, M20, N33, N40, what looks like an AM radio although it is claimed to be an AM/FM, U57 8-track. Manual drums, but testers of the day had no complaints about the 11" drums. No factory gauges (on a budget no doubt) but at least there is a vintage tach on the column.
I think the car would clean up really nicely, but the question is do you repaint or do you simply clean it up the best you can? I don't see the rocker strip on the car, which may indicate past rust repair on the rockers. What do you expect for almost 50 years of existence?
