In almost 200000 miles of daily driving, I have only had to perform regular maintenance, except for:
Electronic throttle (replaced at 118K)
Trunk struts (replaced at 64K)
Radio power antenna (replaced at 165K)
My Volvo dealer has said to me that the most important thing is to DO your maintenance when it's supposed to be done - it's not as important as to precisely what you do (specific brand of oil or spark plugs, for instance) as it is to so whatever is required, when it's scheduled. I have followed this advise religiously and have a quality car that has many thousands, or hundreds of thousands, of miles left in it.
Oh, and I use regular oil, changed faithfully every 5000 miles. And the car burns regular gasoline, too.
I have recently gone through a series of high mileage maintenance items, some of which are not cheap (motor mounts, for example) - but they're much less expensive than buying a new car, and they are to be expected. In the overall scheme of car ownership, the cost-per-mile has been very good - and what I spend on maintenance is money that I don't have to spend on a new car.
Maybe I just got lucky - but, then again, maybe the car has responded to being maintained properly.
