Changing oil and oilfilters, tyres, maybe yes. Changing engine an Boxes, mostly no. Even maintaning a gearbox or valves, no. Here in central europe a modern fleets maintanance will be outcourced, unless your can run a medium sized garage from it. But no fleet is that big. A small garage will not run profitable enought. But Oslo seems good location for a lot of jobs, same as Stockholm and Helsinki - in fact my first garage was Dusseldorf, I think, which is pretty much in the middle of the continental Europe area (of the available ones, that is).
