Coupè.

Fastback Spitfire with rear hatch and the 2-litre Vitesse engine with its twin Strombergs. Options include wire wheels and overdrive. It touches 105mph, 0-60mph takes 12 secs, and it offers a potential 25mpg, but this time the Herald back end is being tried beyond its endurance, and the result is hairy handling and a bumpy ride. Go for later Marks, or modify.
