Was looking over a new Mustang maybe 08 the guy came out I said looks sharp how do you like it ? he said it was OK .............then he started it up it sounded bad.. a funny chinzy type of metalic noise ? it was an 8 the exhaust was fine not loud just the spinning of the motor when he turned the key it didnt sound like a Mustang ? do these new 3 valve motors have problems ???
