It has been a few years since I was in Los Angeles, but is this Mustang the one that is located at the restaurant just east of LAX? There are a bunch of aircraft on poles outside the restaurant and I cannot remeber the name of the restaurant.
Yup, Jeff is right! It's at the "Proud Bird" (Tallichet) just short of the approach end of 25L at LAX. It's a model (rather large scale).
