I bought the 2.5T and splurged for the sport, luxury and comfort packages to get the 17" wheels and leather as well as other feature. The car looks great (metallic black and tan leather with wood appointments) accelerates quite well and is extremely comfortable for longer commutes. I was looking at the Infiniti G35, but I was able to negotiate a much better deal at Volvo and was surprised that the Volvo was only marginally slower with better looks and comfort. I was surprised to learn that you can use regular unleaded in the S60. The only sour point is the turning circle is on the poor side, especially noticeable when parking. Overall I love this car.
17 inch wheels and the optional shifting is fun at times, The seats are extremely comfortable and the acceleration is plenty for just about any situation. Paid almost 5k less than sticker.
The base radio could be better sounding. If I could do it over I would get the better sound system
