I like the Kia Rio
It has the lowest price of all cars, when you combine financing, insurance, and fuel costs. The Rio5 model has an extra hatchback in addition to the regular 4 doors, and the seats fold down for larger cargo carrying. There are pictures with sheets of plywood fitting inside, though they may have to be cut first. It's a shame that insurance for small cars is so much higher than for trucks, because it obliterates any money saved on fuel.
