I've just got an XC70 D5 Auto Est. In your budget, 91k miles. Got the "big car" feel to it, the AWD helps. Rear load area just a little bit on the small side compared with an Omega Est, but not dramatically so. Plenty of power, seems to do what I want when I want. Better MPG than my 3.2 MV6. Some diesel type noise. Nice "solid" feel, you know doors that go "thunk" instead of "clang". Good sound system (HU850). A couple of great toys, headlights adjustable for driving abroad ! Cool. When open drivers door the seat auomatically moves back to give you more space to get in. Maybe this stuff is normal now in cars at this level, but they are new to me
I do prefer the more upright driving position of the Omega, I've fiddled endlessly with the seat settings and not got it all quite right.
So far, very happy. . . . . but the MV6 is still sitting in my drive in case I change my mind. Very unlikely though.
PS: I bought it from my mechanic who thought it was a bit dull to drive. I do see what he means. It's not exactly dull, but it does not drive say like a BMW or a hot hatch, or even like my MV6, just a nice steady motorway cruiser. And yes, it is very comfy
