If the forum was changed to 1M and 1series seperately then who would the M guys brag to? It be like
Person 1: yo, my car's better than yours.
Person 2: Dude, I have an M too
Person 1:Oh, awesome! It's so good!
Person 2: Fo sho, it's like the bestest ever
Person 1: Sure is, nothing can beat it... period. If something does, it's still not as good
Person 2: Hells yeah!
