You may have read this elsewhere, but Tom Donney Motors is creating a museum dedicated to Saab cars in South Dakota, USA. His web site (http://www.tomdonneymotors.com/personal-stock/) says these are from his personal collection, which is quite impressive. It includes the oldest Saab in USA as well as NG 9-5. Personally, I do not mind not seeing 9-7x there, but it should include 9-4x.
It opens in two year. Definitely something to consider if you are going to see Mt. Rushmore.
