There are tons of old functioning car engines out there. Go check out any state that salts their roads, the bodies of older cars are almost gone but thanks to the consistent oil leaks and oil spills over the block the engines are generally clean underneath the grime. If you don't got anything special that people like to tune up and it doesn't self destruct for being a shitty design then there isn't much demand for them, most of their cars are scrapped with another 150K miles or more left on the block.
