S60 is a very nice car, I considered one before I bought my Is300h.
I have had Volvos for the last 9 years & they have been trouble free really other than a couple of recalls, if you can find a good dealer for service etc it makes all the difference.
The menu system can be a bit quirky, but like everything it becomes second nature after a while, a bit like the Is menu.😊
Enjoy the car.👍
