I have a friend theat totaled a '97 BMW M3 on a test drive. The sales man told him to hit the gas in a turn, and he did. The car slightly over steered, he corected, he said the car seemed settled, then headed over a curb and into a tree. This was in a slight drizzle after a rain. My friend is no strange to over steer as he has a 525 RWHP supra with a Tien suspention. The theory is that the active traction control was a little to active. Needless to say he cant buy a car at that dealership.
