If you plan on owning a car for a long time, you’ll keep up on the auto maintenance so that you can avoid costly repairs down the road. But, if you know you’re only going to have the car for two or three years, you may not be so committed to maintenance. It would be easy to think that skipping an oil change here and there wouldn’t ruin a brand new engine. Then it’ll be someone else’s problem when it comes time to pay for the damage.
