Transformers MPL-01 MasterPiece Convoy with Voice Base One of my friends asked me the same question yesterday. Well, since he is a big fan of autobots especially of Optimus Prime, I doubt why he asks me for suggestion of his well-known toys. haha. BTW, the design as I see is special. but I doubt if it is avaible and can be kept for long time. Welcome anybody who have bought and want to comment and give suggestion. THX alot.
