Important to note that for the initial run of NFGT's the no-sale provision was not attached to the CAR, but was a promise made by each BUYER to Ford (at least twice) during the application and ordering process.
Despite what language his dealer purchase contract may or may not contain (see the Jalopnik.com story for details), John Cena broke his promise to Ford. The legal system will get to decide if his promise was legally binding.
On this Mecum car, it appears the seller/consignor was not this NFGT's original owner. If true, this consignor made no such promise. Neither he nor Mecum were subject to any no-sale provision. The question that remains is: Did the consignor acquire the car legally?
If its original owner violated a legal contract with Ford by selling the car, and if the consignor knew that, the sale could be unwound, though the process would take months if not years.
Finally, it is somewhat telling that such a rare, high interest, high visibility car would not be featured nor even appear during the televised auction coverage. The TV network didn't just "happen" to be in commercial when it rolled across the block. Hmmm.
Following the Cena debacle, Ford uses the representations made in the buyer application/ordering process to place a lien on each NFGT at purchase. That attaches the no-sale provision to each CAR, and not just to the buyer. That tightens things up greatly.
I support Ford's efforts and great lengths they've gone to try and get NFGT's into the hands of owners who will drive and enjoy them.
