I just purchased my new 2012 XC60 AWD. It is not the R or T6, just the regular AWD XC60. I came out of a BMW 335i and while I love my new XC60, I feel it is a little underpowered. I am wondering if it is possible and recommended by you all to do the Polestar upgrade. It will cost approx $1500. I have heard those with the T6 did it and love it but bot sure if it possible or advisable for mine. Any thoughts or suggestions would be greatly appreciated. And yes, I know it will never come close to a 335i.
