>>10406369CM's are the best for rally cars, they're rarely to come by though (defunct brand). What I like about them is that they offer a whole set of rally line per manufacturer and lesser known wrc cars, pic related their Subaru line
Right now Tarmac, MiniGt and Inno64 are the best for true 1:64 rally. They're also getting better and better with each release to the point I stopped collecting CM's.
