my 20th anniversary chest halves closes fine but in truck mode the cab dosen't fit together right. It looks like the cab is leaning foward and there are some gaps of space in the cab. My 20th anniversary movie edition prime is perfect everything fits perfect it must be because of the material each figure is made of maybe.

 

you can see pics of the problem at seibertron, here are a few

 

blue paint is chipping off of the legs on my hasbro mp prime. like, rly bad y'all.

 

I don't have that problem eith my 20th Prime, My problem is i can't open the right side window, Left side opens fine, right side will not open no matter how hard i try.
Anyone else got that problem ???

 

I have a problem similar to that, Nemesis, in that one side (the right, when you're looking at him head-on) is much stiffer than the other side. So stiff, in fact, that by moving it, you strip the paint on one of the hinges.

There's a slight misalignment on mine, but it's not that bad. My biggest peeve about it is that the cab doesn't line up properly with the rear section.. because of the way the elbows push against the hips, the entire cab leans forward slightly. Think they would have fixed something like that, since it's rather glaring.

 

Same problem with my window. Right chest piece doesn't right fit. But no probs on opening & closing.
