I only looked up one of your cars, the nerve hammer c41... even though it says 1990 it is a series reproduction of another car. It is actually a 2011 model. Just thought you might want to know this so you do not have any complaints later on. Hot wheels did this to several cars and if you don't know what your looking for you wouldn't know the difference but to collectors these cars are not valuable. It is still a beautiful car no matter what I hope some young child has a lot of fun with it!
