CM's is a rather strange name for a brand of diecast and it doesn't make it easy to search either (try it on my website for example). But these difficulties are worth searching as they do some fine miniature cars.
Normally, the introduce cars by series, like Lancia, Toyota, Subaru, Ford, but also Colin McRae, Rally of Japan...
I believe this one of their earlier products, a Lancia Stratos. The antenna is something you need to fit yourself.
This is a later one, a Mitsubishi Galant VR-4
As you can see, they're top of their class in 1:64 and one of the few in this scale that do rally cars.
