Saw the episode the other day. They did a ton of nice work on it, but I must say honestly that all of it seemed wasted given the woman who owned the car (if you saw the episode you'll agree with me I'm sure).
Damn, couldn't they have found a guy/gal whose M3 needed some tender loving care, and that would have truly appreciated the new level of performance they built into the car? [???1]
Somewhat of a waste, but oh well.
