Very Cool...I have the 79 Esprit with a 301, spoiler, rally wheels, rear spoiler, tilt steering, and T-Roof...no AC or power windows and mine never had the gauge package or the split tail pipes and it has been in a pile unbolted parts for close to 20 years now...I also intend on making it a T/A clone but the body was in too good of shape to pass on it. I'm in Northern Ontario Canada so rust free cars are super rare.
as mentioned and was told to me, the Esprit is rare, yes, but not really that desirable so it makes it harder to sell afterwards if that's your intent. If you intend to keep it then that isn't an issue.
Good luck with it
