My son wanted this for his 10th birthday. Had to shop around a bit to get the best price. Quite an expensive bit of kit but great all the same. he spent most of the day building it and although its meant for slightly older kids, he had no problems working out what went where. Cool engine that has moving pistons and a couple of motorized parts such as doors and boot. The only problem (as we had with the jet fighter) is that he does'nt want to break it down to build the alternate car. Another slight gripe is that you need to download the alternate instructions from the net. At this price (and it was'nt cheap) i would have expected them to include the alternate instructions.
He loves it though and plays with it a lot. He wants me to buy him another so he can build the other retro looking car - i wonder how many other kids are saying the same to their parents - nice marketing there Mr. Lego!!!! All in all i'd say its a great educational as well as fun building toy. He now wants the bigger ones that Lego has just brought out - maybe i'll win the lottery this week!
