Got one for a few days as a loaner from the dealer. All I can say is wow. Volvo finally put together a sports sedan that can easily compete with BMW and Infinity.
I have not driven a new new car in a long time and things have really come a long way.
I got on the freeway and the turbo easily made passing fun and easy. This might sound silly, but I was really impressed that the stereo synced with my Iphone via blue tooth and I was able to listen to all my pod casts, pandora, etc. I'm easily impressed.
It seems like there is a BMW 3 series in every driveway and the S60 is a good alternative IMHO.
