personally, i doubt that I would buy a Maybach, even if I would have billion dollars.. WHY? BecauseMaybach is kinda car where you suppose to sit in the back, the guy in front of a steering wheel is you servant. So.. for as long as I like driving my own cars I'd prefer other cars,
EDIT: actually, when i'd have billion dollars perhaps I'd buy one just in pure sence of owning this car... Nice to let drive myself home when drinking ina restaurant for example.
