It's certainly cool - but for a true survival-type situation, I'd want something old (pre-computer) without an ignition system that would be fried by an EMP, with a simple cast-iron V-8 (or straight six) or a diesel. Something rugged that could roll and not be much worse for wear, once you turned it back right side up.
Something like an old Land Rover 110, Ford Bronco, International Scout, etc.
Hell, even a VW Thing.
Those will go almost anywhere, are incredibly tough, take amazing abuse and continue running - and are easy to fix in the field.
Anything modern is going to be a real liability if you don't have access to the infrastructure of modern life.
