Let me get this straight. You have placed an order for an M5 but since your father doesn't seem to like it you are thinking about changing your order and buy another bimmmer, right?
OK, before I delete this thread I'll just explain, this is a gift from my dad hence my dads $$$. I know many of you probably won't believe it, but I really don't have any way to prove it.
Just as an eg, my brother got an SL55 for his car.
