Both factory and extended car warranty do not cover all vehicle repairs. Extending the contract also comes with a high price. However, there are various types of comprehensive car warranties, which cover specific parts of the vehicle. It will be a financial burden to extend the warranty on all parts of the car. Your car may not undergo expensive repair on a particular part of the vehicle when you cover it on your warranty. Well, whether vehicle service contracts are worth it or not, depends on what you want and the issues your car develops during the coverage.
