I agree the large wheel just don't look right. The 1960-70 cars are a lot smaller than today's mustangs, camaros, challengers. 17s are probably the sweet spot for this vintage.
Plus they are lighter, take less hp to accelerate, less unsprung mass, and can survive a pot-hole.
I like the restomod thing. There will always be pristine cars, and they will be valued very highly. And probably parked.
But the better driving restomod will be used more often and that's a good thing. This one..... Chevy LS-1 engine in a mustang? Really? There aren't any good ford crate engines? That probably hurt the resale potential more than they can imagine. Ford vs Chevy.
