I own a 2008 Saab 9-5 wagon. Its been flawless so far. All of Saab's cars are recommended in Consumer Reports for 2008 and probably 2009. Its a blast to drive as is great on gas. I don't regret buying one bit.
If someone decides they want to buy one of these older Saabs, I highly recommend you join a Saab club. There is a Saab club of Canada as well as Regional Clubs. They have email lists and often other members know how to fix any problems. They can help with diagnosis and how/where to get it fixed as well as getting used parts.
Some will even come over to your house and help you fix it!!
Just google Saab Club of Canada...(sorry it wouldn't let me post the link)
