I'd recommend Madsen Motors http://madsenmotors.com/ in Cary (just outside Raleigh). They deal in only high end used cars and are very meticulous. We bought our '08 9-3 Aero there and use them for any service issues.
Just had my coolant, trans fluid, and oil changed at Patterson Performance in Raleigh today. There are 20+ saabs in the front lot with a couple alfa's as well. The owner was really friendly, and he also looked at a small issue I am having for free. I was very pleased with them and they will be my go to shop for all the maintenance and work needed on my two saabs.
