Another stupid newbie question

Why can't anyone order their car from the factory WITH the FR supercharger? It would be SOOO hard to explain to my wife that I want to spend another 5-6K after the cost of the car for more HP. But if it "came" with the car already, well then, that's another story! I submit to my experts!
 
Have the dealer install it and add it to the sticker price. As a matter of fact, have them put two on there so my wife doesn't bitch at me either.

Or you could always just buy a GT500.
 
Dealers install all kinds of parts on brand new cars and roll the cost into the loan. No difference with an FRPP blower. Have the dealer figure the parts/labor into the deal and pray the bank will do the loan with the extra cost added in.
