This one is a "must see" . Make sure you know how to get there as some GPS instructions will send you down some long dirt roads. This place requires at least one full day. Get there early when they open and stay until they throw you out. If at all possible, go for two days, it will be more relaxing. Car clubs use the grounds for many events even after hours. The park like setting and restored barns are good enough to visit even if you don't like cars.
My opinion
