    Hey folks, I am a new member of the board and new owner of a BMW. So far I'm lovin it and can already see I am probably going to want to move from my 07 to an 08 in 2011!! Real question, what gives the added 100 HP from P400 to P500? I have searched here and have not found anyone else ask that...
