this is actually kinda funny,

"How many years did the 7 dominate? Dunno, but, factor in the number of samples vs the competition, and there might be some logic there. (As in, lots of 7s, not that many Z cars, all things equal, the 7 wins more.) And think about this for a minute , your comment makes an excellent point,...."

replace "7" with "bmw" and that same argument was made several months ago and shot down.

ya have to ask "why were there so many 7's?" maybe because they were perceived as the "dominant" or "fast" car to have? cars don't show up at the track in volume if they are percieved as mid pack or slower.
