I have a 1/16 Lambo by them which i shelved a long time ago because of similar fitment problems that u describe. They would make excellent models but require a hell of alot of work to get them looking good. One thing that is particularly bad with my kit is that the two mold halves were slightly off - perhaps worn or poor tooling - which means that every piece in the box needs to be filed,sanded or scraped. As u can imagine their are hundreds or parts and i'm just not prepared to put the time in for it, hence why it sits at the bottom of my cupboard.
