Best solution for car to "bridge the gap?"

So I'm expecting my M235 to come in late October which means I'm going to be out of a car for about a month and a half. Has anyone found creative ways to find something to drive for the short term. Right now, my best option is the local Enterprise where I have a corporate account. It's going to run upwards of $800 a month for a compact though. Ideas?
