I wouldn't suggest it. They can take a beating, but not like some an mt and definatly not like a buggy. IMHO, the ST is designed for racing only. It's low to the ground, soft suspension, corners really well, high hp to weight ratio. It all adds up to a quick corning, fast at taking off and low flying racer.
If he wants to bash with you and your maxx, he's going to be doing more sitting and watching than bashing I'm afraid. They go ok in grass (short grass... i mean really short) and they can jump (3 feet at the most without damaging stuff quickly). Like I said, if he wants to bash where you bash and drive like a maxx drives, get a maxx, or better yet, get a savage. A savage can take more punishment and has a bigger engine and room for a bigger yet engine.
