^lol thats so great..hahah..
i knew it 450 hp.. i was told by a MB salesman..
so its
450hp and 600nm vs
M3´s 420hp and 400nm vs
Rs4´s 420hp and 430nm
To hell with the 30 hp power advantage.. okay that is gr8..but look at the torque.. its a HUGE diffrence..
now lets pray the C handles.. if so..it will be one heck of car..
