RMZ City is the name of a new diecast company that had an informative booth at the 2012 German Toyfair. I have finally been able to track down a few examples, although they are pullbacks, this does not bother me. I hope you like these as much as I do.
BTW....I have 2 of each color available for $4 each except the red, which I only have one available. I except Paypal.
