If you want a 2nd car that has a lot more room, why not go with the 4-cyl Vue? From what I've been told, the '06 will have the same 2.4L Ecotec as the Sky, and if you go with the manual, it may even have the same tranny (although that's a big guess on that one, and you may want to get an automatic if you're going to be sitting in traffic a lot). It gets pretty good mileage, has a LOT of room (more than any of the ones you listed), and starts around $17.6k. You could add a few creature comforts and still be under $20k. If you wanted to get an '04 or '05 you could get one WAY cheaper, probably even get the V6 FWD for around $20k. They're cheap to insure, too.
