With the number of tradies etc who are making a killing nowdays, dealers can not afford to judge ANYONE who walks in the door, ie the father in law, went into BMW to buy a M3 after a hard day at work, wouldnt even give him the time of day.
Their loss, 2 weeks later he was driving a new m3, purchased from a different dealer.
I once went into a subaru dealer to get a price on a liberty GT, and the dealer told me "the brocure costs $30", yeh f$%k you mate. So I got the ford.
