My son is OBSESSED with Cars and his favorite is Mater. This little lego set is so cute! He loves it. At first it was hard for him to put the little missles in the gun thing but after about a week he was a pro at it! I do wish it came with a little attachment that had the tow part of Mater (like in the Big Bentley set) so that he could be an undercover Mater and I don't have to buy the other set... but other than that NO complaints! Nice little set for a good price!
