My father had underpowered 4-cylinder Sunbeam, Fiat and Triumph sports cars when I was learning to drive. In 1966, I dragged him to the local Ford dealer who had a brand new 427 Shelby Cobra on the showroom floor. It was more than twice as expensive as his foreign sports cars, a whopping $8,000! He didn't buy it and partly thanks to his decision, I'm still alive.
