2tall,
The F50 was $500,000 big ones. I think the program was $250,000 down and $250,000 2 year lease if memory serves. You could not sell for the first 2 years, had to own at least 2 other Ferrari's, and have a great relationship with a Ferrari dealer. These were the requirements, just to purchase an F50. Even getting say a realistic $600,000 now, you lost a ton of money. $500,000 invested in something safe would have doubted to 1 million in that same time span. The way I see it, you lost $400,000. Of course you got to drive an F50!!!
I think the F40's were $250,000, in 1989.
* If you look at the big picture, even these cars were/are poor investments. Automobiles are poor investments, PERIOD. You just have to try and cut your losses as much as possible.
