We also own an 04 XC 70 and I do not like driving it so I was pleasantly suprised by the S80 and the different feel it had in comparison. It has great styling and it is nice to drive. The interior is quiet and the sound system is good. The engine could use a little more go, as we never test drove the 8 cyl or turbo but would recommend doing so. It is economical for gas (why we chose the 6 cyl) and love the AWD.
Offer some more technology in the options like some of the others in its same class.
