Previewed in 1968, and really made for mainland Europe, the rare two-seater Open GT was only available in LHD form in the U.K., but what a pretty little car! General Motors' Opel GT was the only true sports car that Opel produced. Visually a mini Chevrolet Corvette - also from GM - the GT used the same platform and suspension as the Kadett, and while there was a choice of engines in Europe, only the 90bhp 1,897cc Rekord unit was available in the U.K. Although rare here and rather expensive at £1,882 against a Triumph GT6 of the period at just £1,287, total production of the Opel GT ran to just over 103,000 - enough for spares not to be too much of a problem. Performance was brisk, returning a top speed of 115mph.
