Im new here and also new to AZ. I just bought a brand new 07 mustang coupe. I have joined so that maybe one of you guys can help me with a issue Im having. The sound its making is like when you put a card in a bike tire? Have you ever heard that b4? I hate taking it back to the dealer cause then ill be without my baby for days. I cant be without my baby lol. Any suggestions? THANKS TRISHA
