Sir, We are sorry that you did not feel you received the most for your money during your last visit. However,as you may recall, you came in with a " check engine" light on. The first work that was performed was a complete electronic evaluation and physical inspection of your vehicle by a paid mechanic. That inspection noted several faults, including worn brake pads and inner tie rod which you chose not to fix. Also found was a very dirty air filter which was replaced but not noted on your critique.The windshield wipers installed were Jaguar specific and not the off the shelf kind you would get at the "big box" store. They will do a much better job. We hope we have better communication with you in the future.
