Someone on this thread remarked disparagingly about a "glorified golf cart," but given your budget constraints you should seriously consider a street-legal electric golf cart. They're cheap, and reliable. Of course, they're golf carts, so they're slow, and don't have a great range. But as a second car, or for someone who doesn't travel much every day, it can be a practical solution.
Watch out for cold weather, though -- it'll drastically affect battery performance unless you warm your batteries.
