Need an "affordable" family car - recommendations?

Some good ideas - hadn't thought of a Lesabre. Did not realize they got that kind of mileage. A lot of other good ideas as well but the main thing I need to stress is my budget for finding something. I simply don't want to spend any more than I have from the sale of my truck. After going through bankruptcy, I NEVER want another payment on a car or credit card. If I can't save for it and buy it for cash, I don't want it.
