Bought for my 5 year old who is a big fan of Lego and cars in general. In fact, he can build it himself and enjoys it a lot. The guide has some interesting theories and experiments that kids can do to learn some of the principles. This part is probably more geared towards older kids though (although my 5 year old is experimenting with adult guidance). I have enough parts to build one of these at once (I was hoping for at least 2). - Many model instructions are not included so you have to go online to get them (which was a disappointment for my son as the first thing he wanted to build, there were no instructions in the box) Did he end up with the Sharing will build his own model (or at least modify existing ones) is still an open question.
