It was the 1960 MotorTrend Car of the Year, but the Chevrolet Corvair would go down in history as one of the most dangerous GM cars of all time. Manufactured from 1959 to 1969, the Corvair's legacy is a mixed bag of failed reputation and collector's fanfare that can be confusing at times. Many car lovers share an affinity for this "Poor Man's Porsche," but if you ask the average person, they'll tell you to steer clear of the Corvair.
