If this car can be anywhere near as good of a DD for every day driving as our M3s, I will have to consider this in the near future. Amazing that car isn't subject to a Gas Guzzler Tax, but we are.
This bring me to my next point/question. Jeremy Clarkson said that the current generation 5-Series is darn good, that its hard to justify the extra premium for an M5. So is the GT500 worth the extra $10K-$15K premium over a Boss 302? I've never driven either, but I've heard nothing but praise for the 302.
