The first of these fiascos was the Chevrolet Corvair in the 1960s. Introduced in 1959 as a 1960 model, it was initially very popular. But before long its quirky handling eventually earned it the reputation for being unsafe, inspiring consumer advocate Ralph Nader to lambaste it in his book, "Unsafe at Any Speed", published in 1965. Coincidentally, by the same (1965) model year, suspension modifications and other improvements had already transformed the car into a perfectly acceptable vehicle, but its reputation had been sufficiently sullied in the public's perception that its sales declined over the next few years, and it was discontinued after the 1969 model year. During this period, it was also somewhat overwhelmed by the success of the Ford Mustang.
