6-8k gives you a good budget a used Camry or Corolla
8-10k can give you a bunch of options like a RAV4 or Highlander depending on what size you want

Look at Toyota first, then Honda. In those price ranges you are going to be looking at units with 100k plus miles from the middle of the previous decade, so maintenance records are going to be a real plus. Regular service goes a long way with these vehicles. It makes them even more bullet proof. If you find one you like, don't get cheap and not take it to an independent mechanic like Scotty to get a serious look see done. It will be money well spent.

Absolutely stay away from German cars, no matter how tempting. They will break your heart, and your bank account.
