Sometime in the last year, I found (and lost) a website that documented a whole range of planned cars that Jaguar intended on making in the 1970's that included plans to build both the car that would be the XJ-S as well as a proper replacement for the E-Type (had the bottom of their finances not fallen out).

I'm wondering if this rings a bell with anyone else? If you have the URL, could you reply with it?

Thanks in advance,
Rhett

 

Rhett,

I'm not sure if any of these 3 websites might be the one you're looking for, but, I believe you and others might enjoy reading them.

Jaguar Heritage

Jaguar XJ-S development history

Concepts and prototypes : Jaguar XJ-S - AROnline

And here is a french website detailing a one of a kind XJS:
