Ah ha, I've just this car in a 1999 magazine, where it is definately listed as a GT Developments Sportstar, based on a Ford Fiesta. GTD developed the car for a middle-east client who then pulled out of the deal, so the whole project was put up for sales by GTD and Midtec bought it; built a coupl as the Sportstar and then evolved the later Calico from this car. Does this help crystalise the situation?
P.S. Quiller, I'm digging the 21. If ever you need a spare Mondeo tail light, I have one in my garage.
