Query: A good birthday gift

This was the only thing my 8-year-old boy wanted for his birthday. Thanks to Amazon.com, I could get it in time. It shipped as promised and arrived on time. He was able to put most of it together by himself (with just a little help from mom in a couple of tricky parts.) I like Legos' focus on making instructions young people can follow. It is educational and satisfying for my son to put it together himself. Of course, the vehicle is made of legos, and so has come apart in a few places a few times during more vigorous play. But overall it has stayed together well and he has had a good time with it. (The small teeth for decoration on the vehicle are kind of a pain, and he has actually taken them off so he doesn't lose them.) I'd recommend it for a Lego, dinosaur or track-vehicle fan of 8 or 9 years old.
