For under 8k you're fairly limited when wanting an awd hatchback or wagon. At least something that won't have a lot of additional costs involved. There are some expensive maintenance pieces that need to be done at higher miles. With AWD vehicles you need to change the diff fluids regularly, for example my Jeep is every 30k miles, and then there are timing belts/chains which can cost upwards of a $1000 to have done.
You might be lucky and find an Audi A3, 325xi wagon, or Saab 9-2x Aero in your price range. There are also lots of smaller SUVs like the Rav4 although they are not very luxurious they are dependable and good vehicles. The Outback Limited is a good vehicle as well but I'd try to get the 9-2x, which is just a higher end re badged WRX, before it but that's just my taste.
