There aren't any 04 Crown Vics that I have seen. The last one they made I believe was the 2000 or 2001 in metal and a 1998 in plastic. The metal one has the old style hubcaps not the new flat ones that are on 2003 and up. Someone else may know more about this than me so please speak up.
By the way, what state does he work for?
