I considered other, like the following:
2008 audi rs4 (too plain)
2009 gt-r (too expensive)
2007 jaguar xkr (only automatic)
2008 infinity g37 (too common)
I was leaning towards the CTS-V, but am even more so after reading these posts. I have a friend with an 07 CTS-V and drives it in the snow without problems. I am not too sure about the Mas even with the "low grip" setting. Considering the cost of repair, 4 doors, and the winter months, it boils down to practicality vs looks for me right now.
