Great shots - thanks for posting.
Wonder if the driver/owner is taking the photo or if the patrolman owns the car??
(Tail panel "flat", convex gas filler and exhaust trim rings, 10-spokes and two-piece vertical grille with emblem and 4- chrome trim rings on headlights - looks like it might be Brittany Blue. Missing deck-lid emblem)
VERY COOL PHOTOS!!!
I'm sure we could narrow it down, but without a name it might be difficult to pin point. We can't see the model either.
Only two Shelby Dealers in Washington State; Metke Ford sold 34 cars and McCollum Motors sold 17 cars. Those number get cut in half if you include just Lime Gold and Brittany Blue. They get cut down in half again when we look at mid year production cars.
Limit those to just 10-spoke equipped cars and were looking at maybe a half dozen cars as possibilities.
EDIT; Looks like a parchment interior. That will narrow it down even more!
