Very nice museum with a lot to see. I visited with my son and we loved it! Take the vault tour if you like history and special insight. The upper part of the museum was nice enough although it won't take very long to see it all (1-2 hrs). Book the tour when you show up as it only goes every 1-1/2 hour or so, then see the rest. The vault tour was insightful and our guide was very knowledgable about all the cars he showed. The tour took 1-1/2 to 2 hours, was all on foot, and there were no restrooms in the vault (lower garage), also NO pictures allowed on the tour. There is a 50's type diner in the same building as the museum.
