Hi. I sugest you include a RX100, RX2, RX3, RX4, RX5 ( Cosmo ) and also a transplant Mazda vehicles ( many older imports with Mazda Rotary Engines ) in your clasification.
Mazda has many other models besides the RX7 and RX8, and Mazda Rotary engines are very succesfull transplant engines into all sorts of cars, from domestics to imports.
I have seen Datsuns, Volkswagens,Toyotas,Suzukies, etc with fast and powerfull rotary engines that can only make a Mazda fan and Mazda factory proud.:)
