Mode of transportation?

I have thought a lot on the issues about zombies, and have made up my mind on a lot... but lets say you decided not to hunker down, or that where you do plan to hunker down is very far away, what kind of vehicle would you choose to get there? Or if you plan to become nomadic, what vehicle then? And lets be realistic, no tanks, attack helecoptors, or hover craft, etc. Also, lets just pretend zombies are real, think of accesability. How much damage would you have to do to an armored car before you could actually steal it and get it going?

I try to ballance speed, durability, gas milage, diesel vs gasoline, off road capability, zombie proofness, how quickly one could get it going, escape, etc, what have you.

Any thoughts on this? I really am stumped here.
