Yes, need more people polling, but I have to take issue with your figure of 6000:
a) not all 6000 registered post or even visit MINI2 anymore
b) not all those who do post even own a MINI, let alone a Cooper S
I would agree that the polls are asking two different things, but not necessarily that the set(s) of people responding are mutually exclusive, eg someone could have had issues with my MINI and still be very satisfied and have posted accordingly in each poll.
Rogerswt did an interesting thing by posting both polls simultaneously. Unfortunately, vBulletin polls - however carefully constructed - won't give you any data to cross-reference. You simply can't draw any meaningful conclusion from both polls.
