Spending for repairs versus saving with a car warranty
While car warranties are not necessary by law (at least in some states), and while you can very well get along without a car warranty, the purpose of a car warranty is to save you money during times when your car would need servicing or repairing.  While auto insurance is made to cover you and your car against accidental damages, it does not cover the basic wear and tear damages of your car that occur from day to day. You might be thinking that these repairs are minor, that you do not need car warranty coverage to assist you here. But think instead about the money that you would have spent to maintain your car for a total of three years, and now think if you had saved that money instead, what you could be doing with it – a vacation, new rims, even put it towards your retirement fund!
How do you save money? If your car is a new car, then most often it is automatically included with the purchase. And all your repairs (check the actual term of coverage though) would be covered by your manufacturer for the time specified.
