My 3,5 year old loves Cars and has several diecast one's. I like like Mater so I wanted the Mater one of course like any 3,5 year old my son wanted a fourth Lighting?!?). One reviewer mentioned that the size of the car was too small but I think for us the opposite is true. Because Mater has the same size as the diecast Lightings he fits perfectly. Being a Lego car makes him also more durable (no missing chips of paint from crashing) and the makers of Lego supply you with extra lights and stuff so losing something isn't to terrible. Also, the diecast ones are terribly expensive (about 7,00 instead of 5,79 for the Lego ones) and with high use and lots of collisions they chip easily so in my view excellent value for money!
