I’m old enough to remember when many people used to work on their cars. Back then it wasn’t at all unusual to see someone either under the hood or under the car working on everything from an oil change to swapping out a starter. These days you need to be an engineer to perform most car repairs since our vehicles have become so computerized. But that doesn’t mean there aren’t some forms of auto maintenance that you can’t still do yourself. DIY car repairs can not only save you money, they can help your car last longer and retain more of its value when it comes time to sell or trade it in.
