30. 1966 Triumph GT6
Based on the wildly popular Triumph Spitfire convertible, this 6-cylinder sports car debuted in 1966 after three years of testing and research. IT was a hit, with nearly 16,00 sold in its first incarnation between July 1966 and September 1968. It was a two-seater with an extra rear seat that could be ordered for small children. The 6-cylinder engine generated 95 horsepower and a top seed of 106 miles per hour. The legendary Giovanni Michelotti was the designer of this tough little number.
