Hi only saw this thread yesterday, so probably dead news. We have owned 3 SAABs over the passed 17 years. Mainly chosen because they a re very cheap here in Australia.
The first one was a a 1994 900s manual 2.3, was a great car for long distances in Australia and had amazing luggage capacity, traded it at 170.000 kms on a low mileage 2004 2.0 ARC sedan, now have a 2009 2.8 V6 Turbo Aero. this car is at least as quick as our Boxster in a straight line and a slingshot when overtaking.
Parts are not a problem here and reliability has been good, biggest issue was cost of fitting a set of plugs and coil packs due to difficulty of accessing 3 plugs by the firewall.
