"I bought this for my 5 y.o son. I noticed that the material for the Lightning McQueen is different from the usual Lego bricks are made of. Lighter and does not have the feel of super quality bricks that you always get from Lego. I don't know whether it is because it is a Junior set or Lego tries to make this set affordable by lowering the standard - which would be a let down. I bought my son the Junior set, the Police Station, 2 years ago and all the bricks had the same material quality as the other Lego set. That is why I am disappointed at this particular set. I always expect the best from Lego."
