This range of cars manufactured by Tomica (aka Tomy) are not strictly speaking mini-4wd cars.  They are in fact die cast versions of Tamiya mini-4wd cars in around 1/64 scale.  So in effect these are static display models or cars that you could run on a standard hot wheels track.  Maybe they don't really belong on this site, but as they are models of mini-4wd I decided to add them here.  For one thing its so you don't go making the same mistake I did when I bought my first one of these assuming it to be a special edition mini-4wd made by Tamiya for Tomica which is what the box are implies.  It was only when it turned up and I unwrapped it I found out what it really was.  My fault for not researching it fully and also relying on assumptions on a certain popular Chinese website that doesn't always have lots of information available!
