Having a warranty can always be worth it. The area you live in can sometimes be something to take a look at. An area with harsher terrain, and less-educated drivers - such as near a college campus - are good reasons to have a warranty on your car.

Although extended warranties can be very helpful when things start to go wrong with your vehicle, they can also be an unnecessary expenditure when you add up your premiums based on how much you actually have to use it. In your case you have a luxury vehicle and although its 6 years old, is in good shape and well taken care of. Because the value of these vehicles is held for so long I would recommend a warranty if you plan on keeping the car for years to come.

Depending on the year of your car, you may be able to take it to the dealership and have the computer chip in your car read. These machines typically know how far you have gone even if your odometer is no longer functioning properly.
