I got KO in hand today from BBTS. I haven't painted him yet, but I still feel he needs it (that red is far brighter than it is on the show and that purple needs some more 'purple' and less gray and needs to be metallic). He also needs some chrome/silver along the sides of the front fenders/bumper and his windows need to be blacked out.
Now, all that being said, I transformed him without referring to the instructions (which I've been told are wrong) and all I can say is WOW
! It actually looks really really good and far closer to his show model than I thought it would.
I clipped the front fenders into place on his chest so that they're at a slightly downward angle and got them pushed in as close together as I could and I did up his arms as best I could to emulate the look on the show and he looks pretty darn show accurate (aside from the obvious issues with paint apps and the missing yellow fins inside the chest pieces).
