See if this eeuroparts VIN feature will help European Auto Parts - Wholesale Genuine and OEM Saab BMW Volvo Parts
I recommend that you order on-line with eeuroparts, Saabsite, FCP euro, etc vs local, unless its oil and filters, etc.
The SE model should have an SE letters/badge on the back or sides. The Viggen will have a triangular badge on the side, and if you pop the hood, should be a sticker indicating 2.3l engine vs the 2.0l engine for base and SE.
See if you can find a good local indy Saab or at least a european shop in your area that can/will work on Saabs.
