Purchase advice S60/V70(2) 2.5T/2.5T AWD

Servus! It’s S60/V70(2) with 2.5T or 2.5T AWD. First of all, I focus on cars with less mileage. Two questions. 1) The 2.5T is an engine with a low boost turbo. What does that mean for daily use? Can you drive the car less hot and cold, or is it like any other turbo, with whom you have to drive warm and cold and avoid short distances? Is the engine less robust than the 2.5 suction cup? 2) AWD: how good is it with 250-350 thousand km? Does it necessarily need to be used for the curves or does it hardly bring anything to the curves? What can a repair cost? In itself, I don’t think it’s great to drive off-roading and in the snow, especially if the car has 200hp (and not 300hp)?
