I owned two older Saabs, an '84 and an '89 900s and 900 respectively, and *will never* own another swedish automobile again. The parts were a big pain to find, and they weren't easy to work on. The later model Saabs are basically Opels with some of the nostalgia of the older Saabs thrown in to try and satisfy old school Saab buyers. Bottom line...no way in hell I would buy one.

A 3-series BMW with 80k-90k is just broken in. Those cars with the proper care and maintenance are 250k mi+ machines. Depending on what you could get for the Mustang, you might be able to get into an E46 M3. E36 M3s are getting pretty cheap these days; example: My former roommate asked me about one that his coworker was possibly going to sell for $5000. For cheaper insurance, and four doors, look for an E46 328i or 330i.

I'm not a big fan of Toyota products, so my vote is a no on the IS300. I'd rather buy the original...a 3-series BMW.
