I got this for my 7 yr old son mostly due to a very low price this Christmas. Also, the fact that it was an official NASCAR name car made it something I thought he would enjoy. My son is very good at putting lego sets together but these are NOT LEGOS. The directions, which normally he can do without trouble, are confusing, even for me. We have yet to put it together as we've been too busy. legos are normally something he can do without help and without frustration and that has not been the case with these. If they are at full price, I wouldn't have purchased but would recommend buying lego sets for the same price. You'll get directions that are clear for children to use and bricks that actually stay put when you put them together.
