there are at least two other threads about that guy. and a lot of people have been looking for him. sadly, he didn't get into the official maxis uploads for some reason (nor did the curvier lady in the red dress).
gallery member, zsusensei made an attempt at recreating him and the vampire in the red dress (who is also mysteriously lacking) and that they should also pop up with the searches: "trailer vampire" "trailer vampire lady". not an official version, but a nice attempt at him, nonetheless
