On a limited production thing like the Ford GT you could get away with something like that. With a 'mass production' vehicle it's more difficult. Tesla had the 'get out of it' clause in the original contract that if you could show reason why you should be able to sell then they would let you after certain conditions were met.
But if other things happened. i.e. you loose your job and can't pay the loan and they don't let you get rid of it. Then you just keep driving it and not paying for it until they can repo it. Which can take a very long time and you were abusing the shit out of it the entire time. So they now have a car that has had been abused that they have to sell again.
Not to mention, in some states it's flat out not permitted to block the resale of motor vehicles to others. I know Nevada and New Jersey both *had* laws like that on the books, no idea if they still exist.
Short Version: Casinos were running car promos back then and if you didn't want the car, casinos were only offering about 65% OR LESS of the value of the car in cash. So people took the car and flipped it. Some casinos didn't like that so they put in wording to not allow the transfer for a certain amount of time. And then the lawyers came, then the states just put it in the FU they can sell it law because the better casinos were giving close the ACV of the car and were complaining that the ones being scummy about that were making all casinos look bad.
This goes back to the 80s. Was a big stink about it back then when the Corvette C4 came out and had a MSRP in the mid $20k range. There were a lot of casino promos with them and some casinos were giving something like $15000 in cash if you didn't take the car. Since you could take it and sell it for more then MSRP not allowing sales for a certain period of time was just bad optics. Not to mention the flip side, of you do owe taxes on the full MSRP next tax day, so you could take the car, drive it for a while and then sell it comes April 15th. But, that didn't work if you could not sell the car. It was just a mess all around.
I was in high school back then and a major gear-head, it was a big thing for a while if you were paying attention. If you didn't gamble or like cars you probably never heard about it. But, I can see the laws or variations of them still sitting there. If they can be enforced with a purchase instead of a giveaway or as a contract between the manufacturer and someone instead of a 3rd party who knows. I can see a bunch of lawyers just pointed out that it's just not worth dealing with it.
