I don't mean to downplay people's problems, but this very much depends on the car, your local climate, and your ability to spot problems before they become serious. Lots of Toyotas out there that you only need to budget oil and tires for, and the occasional strut/brake pads/spark plugs as needed every few years. And there is plenty of information out there on which used cars are more reliable and how to spot parts that will need maintenance, if one is resourceful enough to search for it.
