That is a very wishy-washy clause in a contract of adhesion, which was written by the dealer. Therefore, any ambiguity goes to the benefit of the buyer.
I kind of expected it say, "You sell the truck, the dealership takes all profits from the sale plus a punitive damages (arguably unenforceable, but still) for violating the agreement.
That clause goes to your the intent of the day of the day of sale. IT is good in that it does a good job of getting you to agree to repay incentives or allowances the dealer looses? So? Anyone know what incentives or allowances dealers are given for the sale of an Lightning?
So what if you have an "economic downturn," die, or simply change your mind? Without getting into defense of contracts, I'd say you can sell the truck, so long as you didn't intend to, even though you were considering it, on the day of sale.
Finally, harms must be foreseeable. So, it really should say, "any foreseeable harm" the dealer may suffer. It would be great to get the dealer to state they cannot foresee any harms other than the incentives and allowances. I don't foresee any but I am not in the dealership business. Is Ford taking their dealership foreseeable? That would be a big bill.
