#1=Mazda R100, yes it's a rotary, but not an RX. From the early '70s
#2=Mazda 360, like the Subaru 360, this was Mazda's first car over in the US. The Mazda logo on this car is a circle with an "M" in the middle.
#3=Mazda Cosmo, also known as an RX-4, from the mid '70s
There you go, I gotta get some sleep, so bye everybody, nothing like proving Mista wrong.... J/K, now you know.
