Your car isn't just a big hunk of metal. It's your (in some cases only) way of getting around. Due to this fact, it's crucial that you keep your car running, and in good condition. A vehicle maintenance schedule is a very useful resource to use toward doing just that. Most every auto manufacturer will provide a schedule for what services your car needs, based on how many miles you've driven it. After a certain amount of miles, different parts of your car wear down and need to be replaced.
