That is a very nice car! They didn't show the underneath but I would guess it's probably in keeping with the rest of the car. The interior is very nicely done with cloth inserts in the seats. The gray works well there. There is what looks like an electrical plug in the trunk on the driver's side. I'm not sure what that could be for.
Will they get $45K? I have no idea. I think CertifiedLotus got $40K for his freshly restored TC 4 speed a couple of years ago. Hagerty lists the price of a concours 1974 example at $45,200 so it's possible but I think they are a bit optimistic.
