I have heard somewha the same thing when it comes to stangs, only from this angle. Couple years ago I saw a report on Dateline or a show like it about older cars, Stangs were the example, models up through 1970 or so do not have a Metal shield, usally in trunk behind back seat to protect passengers from gas tanks spraying gas everywhere upon a rear impact. Back then the regulation was not in place and the report spoke about how the stang is still so popular and thier were MANY MANY ont he road still and Ford pretty much refuses to do anything about it.
