Dad says one of the 1997 bikes is in the Ducati Museum, Tony O'Neill had another 1997 one in his collection, and there is at least one of the 2000 Infostrada bikes in the UK. A few others have been sold through auctions and private sales in the last few years. Boulder Motorsports in the USA have a Ruben Xaus 2000 Infostrada bike too.
Cheers Lou. I forgot about the one in the museum, I have seen that one but it sounds like a few others are still about.
