Our minivan fits us, the 2 dogs, and (the soon to be) child. We had an SUV before, a Touareg, that was horrible in long term quality and MPG. The Toyota is better on both.
Every type of vehicle serves a purpose.
Duppie-you couldn't pay me to vacation w/ 4 other people in a beetle. Sorry. And I grew up w/ 8 siblings and parents in a 4bd house w/ 1 bathroom. I know cramped!!
The problem with SUVs is the ones owned by the individual commuter w/ no offroad aspirations, cargo or towing requirements, and no family. Wasteful.
