This 2014 Hot Wheels Track Set ($15 USD) arrived around the same time as the Guardians Of The Galaxy movie in theatres. It is a gravity track set that includes a clamp, track, spin-out section, as well as three villain pieces to knock over. They are Ronan, Korath and Nebula. They stand on a thin piece of cardboard with a galaxy print.

The track pieces are:
(4) 13 3/8", black, short side-walls

The set included an exclusively decorated model:

Impavido 1 (Roccet Raccoon deco's)

To test how other cars would work on the set, I used the following Hot Wheels Star Wars

Character cars (2014)

R2-D2 (R2D2)
Darth Vader
501st Clone Trooper
Yoda
Battle Damage Storm Trooper
Chewbacca
Tusken Raider
Luke Skywalker
