While it doesn't stand on its own as a toy, there are plenty of cool collectibles to add to your collection if you use them as embellishments to what you currently have.
Pros
Excellent, durable plastic.
Cons
Because the track's sections aren't securely joined, it dangles slightly, and the vehicles' tires occasionally become wedged in the cutouts, slowing them down. The car's turns require slow speeds because if you let it run downhill, the vehicle would just fly out of the corner.
