This is the '10 Camaro SS (017/250) from the 2013 Hot Wheels series. This year Hot Wheels changed the format of the Treasure Hunts. No longer are they noticeable from a green stripe down the side. Instead there is a small circle tampo with a flame, seen here just above and to the left of the front wheel.

I don't usually wind up with any Treasure Hunts since they were so easy to spot. I'm glad they made the change because I really wanted to find this car.
