The sound system is great and it has a turbo.
2007 Volvo S60 2.5L Turbo
My car rides very smooth and the seats are very comfortable. I've had very little problems with it for being a 12 year old car. My only complaint would be that the back seat is really small. Other than that I love it. It's perfect for one or two people but not a family car. Lots of trunk space and legroom in the front. The stereo works great as well.
