Often if you buy a new or used car you would be issued with some type of warranty coverage.  Whether or not you are satisfied with the terms of coverage provided to you would depend on the use to which you plan to put your vehicle and the period of ownership that you would expect with your current vehicle.  These and only these should be the biggest influential factors in determining whether or not your warranty is right for you.  If you do decide that you are not satisfied with you existing coverage, then the simplest alternative is to invest in an aftermarket auto warranty.  This warranty can be used in combination with you existing warranty to provide an additional range of featured coverage or even to alter the terms or conditions of your warranty somewhat.

The aftermarket auto warranty is a good idea for example if you plan to keep your vehicle for a long time and you wish it to be covered during the majority of this period.  It is also a good idea to invest in the aftermarket auto warranty if you wish your coverage to cover all the parts of your car as opposed to only the listed parts on your existing coverage.
