I wouldn't buy a metro to save it for future value, if that's what you are thinking. A lot more value in trying to tweaking it to 70+ mpg (assuming you do it cost effectively and it displaces something with notably less mpg) than storing it and making sure it doesn't disintegrate on its own.

Nobody can say what the future value would be. 5 digits does seem like a stretch today, even for a mint specimen, but who knows? A predictable return on investment if you use it as it was intended though.
