I'd say somebody hit an extra key and it should be $950. He's not that ridiculous on the other Olivers.
That said,I'm still trying to figure out what it is? The motor looks like a 66,but that's an 88 grille. The hood isn't right for it,it's too long. The gas tank isn't mounted in there right. Looks like quite the cobble job. Or pile of parts if you prefer.
