I've seen it been done on mtv (pimp my ride)

It's really simple. Easy in fact. You just need more money than sense. I'm working on my plane/boat/ car. They say I can have a model of it next year. It's only cost me my 20m lottery win. Bargain.

its not worth the money just go buy a Toyota estima!

Have you got bags of money? thats what it will take. I live in Japan and I have never seen a 4x4 previa even though I see hundreds of them every day. My father in law has one. neat machines for families. If you realy want a 4x4 bus buy the Toyota regius 4x4 it will be a lot cheaper!
