Recommendation on used 90-92 Subaru?

I am looking to buy an older Sabaru 4WD or AWD (is 4wd or awd preferred?) car to commute in - was wondering if anyone might make some recommendations - I see several listings locally for Subarus of this vintage with prices in the 2000-3000 range - are there any models of these vintages to avoid? Thanks for any help, Mike
