The Allegro unabashedly melded Mustang and Cougar design cues with pillarless front and side glass, without even the slightest thought about all-weather protection. A sport bar, somewhat recalling that on the first-generation Viper, melted into a pair of fin-like flying buttresses on the back deck. The press release boasted of the Allegro II’s low 33-inch cowl height and 41-inch overall height–not much taller than the company’s own, ultra-low GT40 race car.
