It's uber rare, and I get the investment thing. Hell, they may not even be a car guy. But to buy it for $50K+ and to sell it for the same price (if it sells for the same price) 20 years later with storage and maintenance of 20 years is not very good. Maybe another 20-30 years?? Now if you did the same thing and held a 65 GT350R and sold it today with 200 miles, you could come out with some coin.
