Range anxiety is real, and that’s something the XJ and E-Type drivers never had to worry about. The new GT will need to address this convincingly if it wants to be a genuine alternative to owning a classic Jag, not just a novelty.
I’d be concerned about the cooling system in that old F-150. The radiator and fan setup might struggle with a Coyote under sustained load. Make sure the previous owner sorted that out properly.
