Microsoft Porsche 959

I never knew this:

Gates and Paul Allen dropped $400,000 each into a pair of aluminum-bodied Porsche 959 sports cars, so Manzi ordered one, even though the cars were never intended to be sold in the United States. Allen and Gates took delivery of serial numbers 197 and 198, and Manzi would have taken delivery of 201 except that Porsche decided to stop production at 200.

I wonder where these two cars are now? ( Except taken from “Accidental Empires” by Robert X Cringely )
