1964 Mercury Lynx "X-Car".
I just knew that someday my misspent youth of model car building would come in handy for something. As I (dimly) recall, this was actually a scale model car, built as one of a group to illustrate a Mark Gustavson article on some previously unknown Lincoln-Mercury Division experimental cars supposedly "uncovered" in 2002 or so. It was all very well done as I remember, sort of an "April Fool" type article.
