I am trying to make the exact same decision!
I am debating whether to buy some Blizzaks and drive the M in the winter, OR buy an old CJ Jeep or International Scout or something.
I only commute a few miles from my house, so the M will probably be okay in the winter, but I sort of want a Jeep anyways. Plus the mag chloride, salt, and sand they put on the roads out here destroys the exterior.
What are you considering for your "beater"?
