The time to buy them is when they are cheap and store them carefully so that in a few years the value may have gone up but don't expect a fast return on the investment!! I have a 1972 Hillman Avenger GT which I know is one of only 7 still in existence but even with that rarity value it's still not worth much actual money
It's certainly worth far more to me than it's cash value!! As is my 180
