I second John Martin's credo on this one. You only live once, and you can't take it with you.
If you like it, buy it, enjoy it. Dont think of it in the strictest terms from any investment perspective.
Also, regarding #4036 at Fantasy Junction.
That is one spectacular Shelby. If you look at the pictures on their site you can't really get the wow factor. You really have to walk in there and stand next to her. That car absolutely
stands out,even while surrounded by some of the best of the classic automotive best, in that showroom. I pleasantly envy whoever owned her and whomever will own her next.
