There use to be a car museum/showroom where they had american and foreign collector cars on display and for sale in the Forum Shops. We haven't been there in a while so it may not be there anymore but it was back in 2005.
This shows the problems with searching the internet. Web sites that show the Exotic Car Museum at Caesars is still a viable venue. Looks like it was still operating in 2008 but I can't find anything past that. Thanks for everyone input.
