I think pound for pound in terms of solid reliability, low total cost of ownership, nice hatchback and sleeping area, gas engine automatically kicking on to recharge battery, fuel efficiency, etc...the Prius is probably the best overall choice of a car to sleep in on long road trips/camping trips.
But something in me is not crazy about getting a Prius b/c so many other people have them. Even though this is not rational or logical thinking on my part! Ever other uber driver has one, etc.... I just don't want to be another generic clone. Something irrational in me just never wants the same thing as most other people have.
Plus I may (or may not) spend a decent amount of time in snow country and possibly on dirt roads (not sure of this yet...depends on some family stuff and choices I need to back where to move and base myself).
