There is a nice review in the March 2012 FSM of a 1/25 scale Batmobile from Polar Lights, and it sounds like a great kit.
However, there is also a 1/32 Batmobile from Polar Lights on the market, which I mistakenly purchased a couple months ago. It is far inferior to the 1/25 model described in this review, I consider it to be a toy, not a model.
Parts did not fit well, details such as the engine, were not included, and the decals were apparently old and practically unuseable- they were difficult to release from the paper and splintered into little pieces when I tried to slide them off.
I was disappointed with the 1/32 Batmobile and just wanted to make you all aware that there are two versions of this kit floating around. Based on the review, it sounds like the 1/25 scale model would be far more preferable.
