You could buy one really absurd Mercedes, or 3 Honda Civics... either way you'll still get to work (of course that assumes that there are any jobs left after the world is done ending, but I digress ;) ). But do you want really want to spend all your time maintaining 3 sets of tires, wiper blades, and brake pads, doing 3 oil changes, getting 3 annual inspections, and paying the state for the privilege of registering 3 vehicles, etc etc etc?
Willful redundancy is not time well spent...
