I went and looked at a 240sx today that was sitting in the back yard of someones house that caught fire. The car had grass grown up all around and a co-worker knows the people that use to live there. My question is how do i tell what year it is? I couldnt see the front bumper to well and i didnt wanan pop the hood and look under. But it did have a HUD. Do only the DOHC's come with heads up? It was a coupe.

Thanks for all the help.
