When you need car repair advice, where do you go? The internet? Ask friends or family? The public library? An auto parts store? A dealership service adviser? Your local repair shop? Where you search for car repair advice and whom you ask may or may not get you the information you are looking for.
If you are having a car problem, you probably want to know what is causing the problem, what it will take to fix the problem and how much the repairs will cost. If you are a do-it-yourselfer, you need to know what parts to replace and how to replace them. If you are taking your car to a shop or a dealership for repairs, you want to know ahead of time what you're getting into and approximately how much it will cost to fix your car. Knowledge is power, and it can reduce the chance of being ripped off on a repair bill.
