You could get him a 2.2 class rig that looks much more scale and can look alost identical to what your son drives. The wheels and tires are closer to scale as well as the wheelbase. The supers are nice, I'm about to build an XTM super. The only thing is, the super class is dying all over the country because so many people are competing in the 2.2 class. If I were you, I would ask the guys at the LHS where the nearest crawling club is, go to a comp, and see what they are running. That way, you will be sure to get the right rig for the terrain, and when he falls in love with crawling like the rest of us, he can compete with the equipment he has. Also, the 2.2 class rig will be A LOT more budget friendly, and there's a thousand more parts that he can customize it with, which is another reason that the super class is dying. So see what the guys in your area are running, and go from there. If he's not planning on competing, I reccomend a 2.2 class rig because there's a lot more places that he can crawl with a 2.2, and since you guys go on a lot of ATV rides, the 2.2 rig is easy to pack up in a little box on the four wheeler and take it out with you to find some nice remote places to crawl.
