Dam!!! You really hate American cars huh? I think the M5 is the best 4 door sports sedan made as far as power and performance is concerned. As far as looks, its all on preference. I dont like the looks of the CTS-V, but the power cant be denied and i think it will win. 12 sec flat 1/4 mile times and that vette engine will pull hard from a roll as well. Im not really looking forward to hearing what Road & track has to say, but more looking forward to seeing two drivers in a real world element go at it.
