I have absolutely no idea why people would lie about this kind of stuff in the first place (yet they do!).
Secondly, the bigger issue is the fact that more than half of the people on PakWheels most probably browse the forums just to tell people they're either lying or their post is a repost. Please, lets get over it. If you think he's lying, just let him go and the thread will die anyway. But what if he really is telling the truth? Not like he said he had 15 Ferraris, as he puts it him self.
Personally, I'd be very offended if I joined a forum and someone said something like this to me. I'd request everyone to calm their nerves and think twice before the allegations that you bestow someone with.
Best regards.
