It also has a clipless body mount design that keeps the body securely attached but easy to remove for all drivers, young and old

Review: Quality truck - I think for the price point, this is the best value for the money. This truck is well built and pretty fast. It doesn't do the best on crawler terrain or taller grass. This is ok though, it wasn't meant to be a crawler. I have had it for several months and am not nice to it, hasn't broke yet. I also like the clip less body mounts. Definitely don't regret this purchase. The picture I posted is with bigger tires than it came with.
Review: Lots of fun - Awesome, fast, tough.
