FWIW & IMHO:
I think that vehicles in general make poor investments. It is virtually imposible to speculate as to what will be collectible 10, 20, 30, or 40 years from now. For every person who bought a Cobra, Boss 429, Hemi Superbird, ZL1 camaro, Mercedes 300Sl gullwing, or whatever years back and made money, there is probably 50 people who bought other cars that they thought would be collectible and did not even get basic bank interest. The odds of speculation on this are probably considerably worse than Vegas. If you can buy a vehicle that you like, drive it for any length of time and not lose a lot of money, you are doing bertter than most. Also, I don't think that it matters whether you buy/collect cars, planes, boats, guns or mother-in-laws, they all make poor investments. Just my $.02 worth, and that taken before depreciation/cost of living suprises.
