That's insane. All you need to do is change oil, change the spark plugs, change the auxiliary belt, and change the air filter (according to my manual). Shouldn't be more than two hours of work with common hand tools (except the belt tool that you'll need from iPD). Your service center should be able to sell you filters/plugs/belt.

This is also an excellent time to change your transmission fluid, but you don't have to. Also think about bleeding your brakes with fresh fluid. Both are great things to do and help prolong the life and increase the performance of your car. Volvo says to change brake fluid every two years, and there's no set period to change ATF. I changed the ATF in my S80 T6 to Mobil 1 Synthetic at 45K and have noticed much smoother shifts. It's worth an hour of work. You won't need anything but a length of 1"ID clear plastic hose, a proper size hose clamp, and a small funnel.
