I think they're pretty cool. The green tank in particular just looks like a badass little TF, without even factoring in his limb-y-ness. Pretty sure I'll get these (don't have the main PCC Bot that's being used in all the pics, but they can go on one of my other ones) and hope that they sell well enough for more to be made. The black Huffer repaint would be an acceptable Motor Master if they knocked up a set of Stunticon arms and legs for him. Or even a set of construction vehicles that could go with either Sledge or Steamhammer.
