I quote from my source:
"The platform of the Porsche 911 was used for a masterpiece, dubbed the 'Diba GTC', built at the beginning of the '70s by a Swiss bodywork specialist.
The two-door coupé had an 0.88 mm gauge all-steel body upon the Porsche 911 chassis with original mechanical and electrical components. The 2-litre six-cylinder engine produced 148 bhp at 6,100 rpm, and the 7 in wide special magnesium rims were equipped with 185 HR 70 x 15 Dunlop tyres.
The wheelbase was 87 in (2,210 mm); the front and rear tracks 52 3/4 in (1,340 mm) and 53 1/4 in (1,350 mm) respectively. Ground clearance was 6 in (150 mm), the length 170 in (4,320 mm), while the Diba was 70 in (1,780 mm) wide and 44 1/2 in (1,130 mm) high.
Without fuel it weighed just about one ton (1,020 kg), had a total permissible laden weight of 3,086 lb (1,400 kg), and the unique GTC had a top speed of 134 mph (215 km/h). Consumption, according to the constructor, was between 15 and 16 litres per 100 km (18.8 and 17.7 mpg).
The interior was taken mainly from the 911."
No mention of the Swiss bodywork specialist's name, though...!
