Saab dealer would but they are Subaru drive train. I think they came with a long warrenty as Saab includes that on their cars. But the Saab dealer is $$$HIGH$$$. I own a 900SE turbo and the part cost are high. And there are a lot of parts that only they can get. Luckly you do better with a indie auto tech and if you need parts call saab AND subaru dealer for whom ever is the cheapest.
They are really good as I think they look much better then some of the Subs at the time but still have the drivetrain since it is just a Subaru with Saab clothing.
