Nice car Mike! Your son is very lucky. My first was a trashed 1969 Old Cutlass with 150K that I had to buy myself.
He was driving a 1994 Toyota pickup with 175,000 miles and was pretty beat up. Then some kids (we think we know who) put sugar in his gas tank. Between that and recent hail damage, it wasn't worth putting the required money into it not to mention potential problems down the road.
I get Ford employee pricing through my company and with the year end incentives, $6,000 of his money, and zero percent interest, it was a no brainer!
