If you are looking to visit car museums in the USA, here is a list not to miss

here is a list of the top 10 in the world: http://www.edmunds.com/car-reviews/top-10/top-10-automobile-museums.html?articleid=122959 which completely agrees with http://smashingusa.com/12-definitely-worth-a-detour-car-museums-of-america/ and they agree that the Henry Ford, the National Corvette, and the Petersen are not to be missed and they suprised me with the Studebaker and the Natl. Auto museum in Reno (formerly the Harrah).
