We are finally moving back to the Denver area and we are about to buy a new car, a Sienna to be exact. The biggest question I have is how much do we need the AWD version? I have always had it when I lived there but probably rarely used it. I have kids now and want to be safe but obviously AWD is a lot more expensive and worse on gas. Does anyone have one? Can you guys advise me on how much you think I will really need AWD?
