I am amazed with buggy durability... and although the mbx-5 looks nice, I would think all buggies are pretty durable. I am looking for cheap, and parts support... something nicely built, but not a race buggy that is super light. I need cheap, parts support, after market (such as pro-line bodies), and well built. I had a raze and it seemed pretty well built... But some cars just fall apart when you get them, i do NOT want that. The thing is that i have never heard of the mbx-5. and I have never seen parts stocked at the LHS... now if it's dirt cheap, and like you said it doesn't break much.. i could always order from an online dealer. A-main is pretty close to my house.
