It's like many new cars when it's new to hold for the sky and then you start to break things you do not hold them on. Oil changes and tune-ups are an important part of car ownership, and like any other, it depends on the owner's car. Some cars are good and some cars are not so good. Try to buy the best low mileage car you can afford and hope it is lasting for a short time. I have heard the story of both sides of the coin held something right, not others.
