The dealers in this case are rent-seekers.
I know a guy here in Michigan who has a 69 Impala ragtop with less than 200 miles on it. He even has the original wheels and tires hung on the wall for when he trailers it to car shows. He bought it right off the factory floor when he returned from Vietnam.
He signed the paperwork before the car was even finished and he drove it off the assembly line.
