S70 or S60?

It depends on what you expect. If you expect a car that "drives" better then the S60 is better If you expect a big rear back room, take the S70...... (to be honest: if the backseat is a matter I would go for a S80) If space in the back is a matter, consider a V70.

For me a S60 2.4T oulb be the first choice. The 170hp is not bad, but a little bit sluggish, a N/A engine....

These are good comments. Keep in mind even though the S60 is the successor to the S70, they are COMPLETELY different cars with a completely different design philosophy. I personally am very disappointed in the S60 and would recommend the S70 to you. But my disappointment falls more in the comments of Juergen Schrader. In general, the S60 "feels" and behaves more like a coupe. I cannot stress enough that if you need any functionality out of the back seat, pass on the S60. The tires they matched with this car are also a poor choice - you'll want to change these quickly. In general, I feel the newer Volvos are more on the "fluff" and less on real substance - more of the Japanese car approach. I have the 2.4 (N/A) with 5 speed manual (168 hp) - at times I would like more power of the turbo, but it is actually quite adequate when matched with the manual transmission. I have had an automatic as a loaner and it was definitely more sluggish.
