Corvair's in mass

On July 19th, we went out to go see this car show and I was surprised with how many Corvair's were there. from looking around there were more Corvair's there than any other make. It seemed surprising I thought there would be tons of 289 Mustangs and vetts than any other car, but no, there were probably 30 corvair's out of the 100 cars there... it was very surprising. My Question is are Corvairs more popular then before
