I bought both the Disney Pixar Car Sets for my grandson from the Disney store for $10 each. The first set includes six characters: Lightning McQueen, Ramone, Sarge, Tractor, King and Luigi. The other set also has six characters: Tow Mater, Chick Hicks, Sally Carrera, Guido, Fillmore and Doc Hudson. They came in an attractive box with a plastic top, which would be nice for a collector to display.
The cars are made from plastic and are approximately 2.25 to 3.5 inches in length. They are nice replica's of the characters from the movie, but are not very durable. Mater's tow hook broke off almost immediately, and that being my grandson's favorite character, it didn't make him too happy. I didn't realize when I bought these that they were not the die-cast cars that you usually see sold individually in the stores.
My grandson really loves having the whole set of cars from the movie, but I would recommend buying the die-cast cars and maybe using these to decorate a cake or for a shelf display in a child's bedroom.
