My 2.5yo son is a big fan of Cars (both the movie and toy cars), and when I saw this I knew he'd love it. No complaints coming from the little guy, but there's something about the metallic paint of these vehicles that don't seem to have the same quality as the typical "Cars" cars you find in stores. Not sure if it was due to a limited production run, or simply due to contaminates in the air/paint. Not an issue for young kids, but may be a concern for some collectors. It looks like each car might come out a little different, dust in the paint, etc..
Very happy with the purchase, and love watching the movie in Blu-Ray. Would definitely recommend to other fans.
