The VW is too advanced for Laddy too (I asked for it for Xmas for myself!). He is 5, and just got some of the Lego City stuff. Man, they really hook you, and you end up spending more than anticipated, because if you get the police station, then you want the robbers hide out, and then you need the bank for them to hold up, and there is the armored truck....it is endless. I have a feeling the fire stuff will be next on his wish list.
But it is really fun to play with. Even for us adults! I never get tired of building with it.
