Worth every penny I paid for it. As for lowered rating for reliability (9), it's due to the window that got stuck and was replaced (for free - it was still under warranty) with the motor, guides, and everything that goes with it. No other problem whatsoever.
Heated seats. Never even thought of that option before it just happened to be there (bought the car used). Now use it daily. The rest was expected to be there - after all, it is a Volvo.
That 6-cylinder from S80 can fit under the hood of V70 as well.
