my wife drives a toyota sienna minivan and she loves it.
but am just not into it. i've driven a big car before - my old 560SEL was just as long and just as wide as the toyota sienna, so it's not the size.
i don't enjoy the way it drives. i will drive it if i have to, but i prefer to be a passenger in the middle row and let my wife drive when we take the sienna.
i admit that it is a fun vehicle when you are going on a road trip with friends. you can all pile into one vehicle and drive together.
