Oh, and does your car have dual pipes in the back? If I recall the i4 only has 1...
BTW I dont think the dealer would try to rip someone an i4 for a v6 because that could get them in some MAJOR trouble if not get them shut down... 
Dude I don't think he's wondering if he has an i4 or V6...were you serious?
