Found a little card I got from SGT many years ago for the EVA GT (still keeping my fingers crossed) the official spec was...

"New four seater coupe, BMW 3.0 straight six twin turbo with direct petrol injection
Rear wheel drive with intelligent suspension, 6 spd sport auto or manual gearbox
40mpg, 306bhp, 400Nm torque, 0-60 approx 4.5 secs, approx top speed 170mph
£70-85k circa tbc"

I think at the time a Roadster was 36k and an Aero 62.5k
