I love my Baja......I run 92 octane in it and the only probs I've had were the rear tires shredding. BUT, I run mostly on pavement so thats my problem. I did have a problem with the rear wheels rubbing but I got the new updated wheels, which should be on all the new ones by now, and haven't had that problem since. As far as breaking parts, I've not broken anything on mine.............yet......LOL........
get one, you won't be dis-appointed....
