I agreee with David. And it seems to me the BMW has some distinct disadvantages that just adding weight might worsen. Like tires going away towards the end of a race. Nothing like getting slammed by 3100 lbs of ungainly BMW that just wore out its tires on the last lap. JMHO. Its bad enough being hit by an RX7 while in a 240z, the BMW would be like getting hit by my tow vehicle.
