My son is 8 and this was his birthday present. He wanted a new body since his was eat up to the point most of it was missing. This is how it turned out, it’s my first one. I bought a Kraton today for me and it’s already torn apart down to the frame. I broke the bumper and a knuckle on its second run. I’m going to rebuild it with upgrades, change gearing, fluid weights and shim the diffs and whatever else I can find on this site. It was fun while it lasted. He is rough on his granite and it hasn’t had one issue.
