I don't see many references to 1966 El Caminos on here so here is one: "Gator": Several scenes show a mid-'60s El Camino in this movie with Burt Reynolds from this website:
http://www.chevelles.com/elcamino/ec_tv.htm As I recall, the car is seen three times
- once in a garage as in service garage
- briefly going by barely avoiding a head on collision
- in another scene I don't recall
This car is a metallic light blue. I own one of two L79, 1966 El Caminos...or I did own it before I gave it to my son.
I'd be interested in other movies with El Caminos in them.
