Hi, re: ??GTD, the above post is correct, that GTD in UK closed and ?relocated to S.Africa. Under Jean Fourie and John Spence, GTD cars were built by the newly formed
CAV (Cape Advanced Vehicles ), reminiscent of FAV (Ford Advanced...).
After they used up the material from GTD, they continued building CAV tube frame cars, but I think they always wanted to take it a step higher. Hence AutoFutura, responsible for the monococque car. I understand John Spence has ?left, and Jean Fourie remains one of, if not THE only DNA / surviving link from all companies.
My car is a GTD-CAV, and I know of two others in America, one serial no. away from mine each side. The car on Ebay is a GTD CAV tube frame car (at least the one that was for sale ending early September 2008).
I hope this is helpful.

Incidentally, my car just had the rear suspension uprights fitted by Ian Clarke, Burlington, ON (posts on this site) and I am very pleased with the quality of his work!
