Someone was telling me that the best performing commodity, hands down, in the last 10 years has been American Muscle cars. He then told me the percentage rise, which I don't remember, but it was like 1200%.
Of course you have to define "muscle cars", it is like talking about specific stocks as opposed to *all old cars* being like the entire stock market. But anyone knowledgable knows which cars we are talking about, ie. big blocks/SS models/hemi or 6-pack mopars, etc...
