I saw the new thing up there where the 500/472/425/368 are all in differnt rooms..... why is that? they are all the same engine... there should be a room for the 500 family, and then the 4.x family, then any other engine besides these 2 catagorys and the N*..... just makes more sense....atleast that's how I see it...

This is being changed now. The only difference is the 500 is together with the 472, 425 and 368.
