As previously stated, have a mechanic you trust service the motor and look for potential problems. If you do decide to extend the warranty make sure you understand what is covered. It will be expensive. I recommend going through your dealer and purchasing the extention from the motor OEM. You may be able to negotiate the premium. I would avoid the 3rd party providers unless your dealer has had good luck dealing with one. It's like any other insurance policy you carry. You hate the premiums, but are glad to have them if you have problems. Good luck!
