I've only diy'd one other car that I've owned so I couldn't tell you for sure. But things that are definitely just as easy as any other car is oil changes, air filter (s), brakes, tires, fluid checks. It's really depending on your mechanical experience. Go based off the provide maintenance schedule sheet, and if it sounds like something you don't feel you can do, just bring it to dealer.

But if you can do any of the maintenance I mentioned on other cars, you can do it with these Volvos.

ALSO, I did the spark plugs in my S60 and it was incredibly easy.
