Like anything European, maintenance and repairs are a lot higher on Volvos. Doing the scheduled maintenance definitely helps, something most neglect.
It seems all manufacturers are putting so much technology into vehicles these days, any little problem becomes a huge expense. I've been thinking about getting a new truck for a while but even if I stick with Toyota which have simpler, more reliable platforms, you have to get all that lane departure and distance pacing safety ****. It takes special equipment just to do an alignment, something my company hasn't invested it yet, although it's coming eventually. But with the added equipment, something as simple as an alignment you should do a couple times a year is going way up in price. The price of vehicles will continue to climb with all the technology but where I think they will really get you is with maintenance plans you will almost have to get in the near future.
