Interesting. I've been on the verge of ordering a V90 - and echo your thoughts on the interior. It would/will be my 3rd Volvo, and like you I prefer the perceived "image" when compared to a BMW/Audi.
However, I've been stopped in my tracks by all the adverse publicity around diesel doing the rounds. As I buy my cars outright and keep them for 6-7 years as a rule I'm unsure where we're going to be with oil-burners in a few years' time. Seems to me that there's going to be every excuse for the bureaucrats to clobber diesel vehicles (or the fuel) with higher tax rates before too long. We may not even be able to drive into many city centres if this continues.
So I'm biding my time until the T8 hybrid-powered version turns up. There's likely to be a hefty price premium unfortunately, but the tech does sound very impressive, and the 8-year powertrain/battery warranty should cover my risk. My XC60 will just have to soldier on a little longer.
