Are you keeping the 4 runner? If so, then anything that gets you from A to B for good mileage would be great, then the 4 runner when snow starts falling in the winter and 4 wheel drive is handy.
According to this:
toyota's remain pretty highly regarded amongst owners based upon reliability. I have a camry myself (as well as a Highlander that my wife drives) that I bought used, and haven't had any problems with it. If I wasn't worried about winters, I'd look into a corolla.
