I went to that same dealer when I was looking to buy a cobra, the seemed pretty stupid when it came to performance stuff.
I said I was looking for a 2003-4 Cobra and the salesman looked at me for a second and was like...."We got a real nice Mustang Deluxe over there and its probably faster"....shortly after I left and never went back.
