Check out this month's Motor trend

It was truly a fascinating series of articles. 911 versus Z06, 911 versus Cayman, and 911 versus Vanquish. The 911 versus Cayman article was pretty interesting. The cornering ability of the Cayman damn near got it the win on the track. It's really only a few ponies behind spanking the 911 on the twisties.

I also agree on the Z06 - it's a hell of a car! World class performance at a "reasonable" price. One thing to note is that every review I've read (including the Motor Trend comparo) mentions that the Z06 isn't necessarily ideal as a daily driver.
