This was my first lego set. It's still suprising how much they could pack into a single set. It could be used to build various vehicles and houses (the set includes instructions for approximately 7 cars, 4 airplanes, 3 houses, 2 ships, a bunch of animals, and even a working windmill with a house and a truck). With the two minifigs the set can be used as part of a lego town. The wind up motor even allows motorized constructions that can't run out of battery. Many models in this set were later used by lego as a basis for town sets, most notably the tow and fire truck.
