I would make sure the hinge pins and shock shafts are gold ... if they are not then its not been upgraded ... I have bought rtr used and new as well as rollers and a kit ... like was said you can run through cash like nothing fixing stuff ( stripped plastic where things wont tighten , bolts superglued and so on ) what scares me is that they say everything is upgraded ecxept the things that you can see . Also and I dont know if its on safetyhawks list the hinge pin braces are machined and not stamped which makes a huge difference in the strenth of the buggy in collision ... I am just saying that I have watched and bought nib race roller for $425 on ebay ... also though if you do get the $200 8ight it could be real nice for parts ...
