Give it a rest. A Porsche will always be a Porsche and a BMW will always be a BMW. If any of you think that a BMW is a better driver's car than a Porsche, you're definitely snorting too much BMW-brand cocaine.
Cars like the M5 and M6 only sell because the guys who buy them couldn't convince their wife on the 911 and/or they don't wanna man up to a real manual tranny.
