I recently found the Zamac version of the 2014 Hot Wheels Chevrolet SS – one that I wasn’t lucky enough to find in stores when it first came out – at the Village Flea Market. The casting represents a GM-manufactured, Brazilian Impala/Opel hybrid called the Opala. I have the dark blue version from 2014, as well as the 2012 first release and a sweet 2013 variation with racing graphics.
I do not have the Treasure Hunt version that came out in 2014, and I just noticed hobbyDB is showing a pearl yellow version that is exclusive to 2016 multipacks. Now you know what I’ll be looking for next.
