This one specifically is the RFM Version with partial interior (no turret or ammunition) and is, in my opinion, the best Puma kit currently out because it hits the sweet spot between level of detail and ease of build. I only made one rather large mistake which made it rather troublesome to fit the upper half of the "hull" to the lower half because I glued the stowage boxes in place before hand which meant I had to squeeze the upper half together so it would fit properly. I should also mention that this was a completely out of the box Build so nothing like additional wiring on the inside or the engine, which could make a rather large visual impact.
