Thank you for your business and for the 4 star review. We apologize for the misunderstanding on the price. When we quote a job we quote how much parts and labor cost, tax and shop supplies are not included in the quote. That is why there was a $100 discreptency in your bill. As a sign of good faith and because we feel that it was a bad on our part we would like to offer you a free oil change on your Crown Victoria! Thanks again.
