Let me start out saying that i absolutely love bimmers.. but...

Im not normally one to call BS but..... BS. the chances of having enough "motor" work to get a 540 into the low 13's high 12's is slim to none. unless mommy and daddy have an amazing amount of money it just isnt possible.

Lets look at the facts:
-dude works at best buy
-he is still in high school
-people in highschool that work at best buy cant afford a 5 series bmw much less a 5 series that runs high 12 to low 13's.

again , impossible? nope improbible? definatly.
