i think that because your so young it is hard to believe for some that you are for "real" and not just trolling. if have pics of your m5 that would be nice. i for one think that it is possible to be 18 and own a m5 but i would think that such a young guy with that kind of money would tend to purchase something like a porsche or other sports car. (unless of course you started having kids at 16 and having to carry around kids in the back! lol). when i was younger i had a lot of friends that had rich parents from overseas and a few of them had ferraris and lambos purchased cash for them before could even legally buy cigarettes or alchohal. good luck to you.
