I recommend a T-34.
Pros:
- low maintenance cost, can be fixed by banging it with a hammer
- if it runs out of fuel you can ask boongs laying about to piss in it, that will enough to reach next gas station
- don't need to know rules of the road, everyone will conform to you
- you can make your parking space on a whim
- aesthetic
- emu proof
Cons:
- in the summer it can be hot, maybe fixable with an AC unit
- in winter can be cold, maybe fixable with installing a stove
- fuel consumption (can be mitigated with the boong trick)
- a little bit heavy
