Hi Rick, hi guys.
A good conversation, I'm enjoying this thread. To throw my hat into the ring here, I would like to make the observation that towards the end of its life, embodied in the 3 series, the E-Type became more of that "Grand Tourer" as opposed to an outright sports car, as it was at its inception. The XJ-S merely followed on from that point, and it was only its unfortunate styling that kept it from being a runaway success, opening the door then for the SL Mercedes to gain in popularity.
I think that the F-Type would have been a success, and that it's only the present economic climate that it really preventing its launch. Remember, Jaguar got their fingers rather badly burned during the last recession, when they were left holding a lot of exotics, such as the XJ-220 and the XJ-R15 that they had to sell off at fire-sale rates and start a racing series for, just to move them. It is,in my opinion, just a matter of timing. We may well see this car once the economic situation has improved again.
