Airliners.net had this to say about the Saab 2000
Lack of sales and profitability forced Saab to cease 340 and 2000 production, with the lines winding up in 1998. The last 2000 was delivered to Crossair in April 1999.
In 2000, 54 were in airline service with three used as corporate transports
From what I can tell, they are only used in Europe as a regional. Hendricks Motorsports does own/use two for Corporate shuttle use.
