There have been plenty of cases where car makers say they are going to build only a certain number, then demand calls and they supply and make money. Economics is a bitch.
Here is what i hope happens. Fords loses the case....wait for it....but the stipulation is that the cars MUST increase in value over a certain time. Here is where the good people of America come in: the collectors demand will plummet making these cars go down in value, then all the douchebags in the case have to give the money back, plus interest for the time and trouble.
Buy a car to drive it, then when you want (or need) to sell it be happy that you can make or get your money back. Buying a car for an investment is great, but not driving it and appreciating it is like baking a cake for your birthday thats 4 years away. Then being pissed that the cake turned to dust.
