I know that a lot of people hate the way the Honda Element looks but they're extremely roomy inside and the MSRP for the 4WD LX is $19,150. They're very durable...rubber floors, water resistent seats, etc...and the back seats fold up or come completely out.
I have the 2WD EX model, which gets 17 mpg city and 23 mpg highway.
