I found this great link for many auto museums of all kinds.

I went to an Auto Museum in San Diego....lots of cars and old motorcycles crammed into a building the size of an airplane hangar.

I've been to the Canadian automotive museum in Oshawa Ontario and the Ransom Olds museum in Lansing Michigan, went there in 1997 when I was in Lansing for 100 birthday of Olds.Both very cool museums.

The RE Olds museum is very cool. There's a lot to see there, from earliest gas engines to even non-Olds products like the EV-1.

Went to the Imperial Palace (Las Vegas) last week. Great cars, but the selling price of most was a little high. One Duesenberg had an asking price of $2,500,000. Highlight of the museum was the old Duesenbergs. It was worth the $6.50 to get in.
