I finally found a custom '71 El Camino, a treasure hunt at that too! It's blue and it looks like it has jet engines in the back, so I'm guessing it's just something Hot Wheels did, meaning it hasn't been made in real life. But either way, it's awesome! The other car is a silver Aston Martin 1963 DB5, from James Bond 007 Goldfinger, another neat casting! Glad I finally found them both!
