I'm the old fart with the XC90
Practical as a practial thing on national practical day!
Getting in and out is OK, but with all SUVs its a bit higher. They are holding value very well, but you'd struggle to get 230+ BHP unless you got the scarily thirsty T6 or rare V8. We got the 165 Pre-Facelift model and remapped to 200. It's no '8 but it's quick enough. You can get up to about 220hp with the newer D5 engines, but not sure how much it really needs that.
It is a bit boomy from the engine at 80+, but not too bad probably just because I'm comapring it to an '8. All 7 seats can take an adult in reasonable comfort (and I mean me... so as to whether they can take a grown up that's another question). Boot is massive, spec isn't that great compared to an '8, but ours hasn't missed a beat since we got it 2 years ago.
