In the late ’60s, legendary Alfa Romeo designer Giorgetto Giugiaro left the manufacturer to start his own firm. The 1968 Bizzarrini Manta concept was one of his first independent design studies. The Manta is built on a Bizzarrini tube chassis, rocks a powerful Corvette V8, and seats three across. The driver sits in the middle—two passengers sit to either side. The thing is only 13.6 feet long (a current-generation Mini Cooper is about 12 feet long) and 41.5 inches tall. It was originally coated in shocking lime green, but was later swathed in smooth silver. According to Supercars.net, today it lives with a private collector in Texas, who had it painstakingly restored and coated in a cool shade of turquoise. Hit the jump for more photos.
