Motorized LEGO Machines
With an interior that is literally packed full of motors, the 5kg LEGO Tow Truck II by Sariel is one seriously powerful machine. In addition to being remote-controlled, the vehicle also has automated lights and a fully mechanized towing apparatus. Needless to say, it is one LEGO toy geared less towards young children than it is their fathers.
Implications - When you see this monster in action, it isn't hard to immediately recognize its appeal. This toy packs a serious amount of power and fun simultaneously, and it would be an absolute blast to drive it around your home.
