To answer a few questions quickly (as I have to go put a new bed together).
The luxury features in the CTS are outstanding, and the RWD is great, that's mostly what it gives you instead of a TSX Jeff, the CTS is more luxurious and a softer ride, the seats were amazing as well.
As Ktm pointed out the CTS seems to have a great turning circle, trying to get into the loading zone at Ikea on the busiest day of the week was a breaze and such a large car I was impressed.
I drove the car today with all-season tires and we had about 20cm of snow. The roads were HORRIBLE, the traction control and stability control kept coming on, it was entertaining to say the least. I would NOT want to drive this every snow fall it didn't feel as safe as my subaru. I'm not sure how much of a difference snow tires would make.
Once I stepped back into my subaru I plowed through some pretty incredible stuff and had no issues, I seriously wasn't moving 2km/h in the CTS and could NOT get traction. That is one downside I'm glad I got to try out, I really wonder if it would be viable for a winter car. Yes you can drive it in the winter, but is it a pain every snow fall??
