While I don’t know about your specific issue, I do suggest to do a lot of research before spending that much money. When I have a car repair, I do the following research: 1) research the prices of the parts from various locations; 2) look for videos online on how to do the same repairs so you get an idea of the complexity and the time it will take to make the repairs; 3) call around for estimates to both dealers and independent repair shops to get an idea of the average prices. In your inquiry, make sure you ask them to break down what they are charging you for the parts and what they are charging for the labor (rate per hour and how many hours for the job). This research will help you feel better about your decision to spend that amount of money, and ease the “female fear” so many of us have. Good luck!
