Never neglect your vehicle maintenance. Having your vehicle serviced at certain points in its life is important for getting the longest amount of time out of it, and if you eventually sell it, you'll also be able to get top dollar for its age and mileage. But you have to know what needs to be done and when your vehicle needs it. The exact mileage and timing can vary from manufacturer to manufacturer, model to model, and even from year to year within the same model. Because of this, you should always consult your user's manual. But there are general guidelines, and we're going to give them to you based on specific mile marks on your odometer.
