My son bought this set with his birthday money. He is 6, not rough on his new toys. Within the first day, Mater's tow hook arm broke off. The next morning, one of Guido's lifts broke off and then the same day Chick Hicks' tire is bent- which now wont roll right. They are just made of very poor quality plastic. I expected them to be more of a "matchbox diecast" and they arent. My son has been so upset daily at this cars breaking, he spent $14 at the disney store on this and its junk! I would recommend you buy the little matchbox ones from walmart for $3.19 a piece! I have yet to find a mater toy that is made for children. We have every item they have sold with Mater on it. We have the RC, which my son LOVES. Its very fast, but all of the little toys the tow arm breaks within hours of purchase! Hope this helps!
