I recently obtained a new to me, Grand Prix and over the past couple months Bill's has been getting it all in order. The car was indicating it needed traction control ABS service and Bills kept checking it, test driving it, and sort of making it a mission to figure out. It was not easy to figure out what was causing it, but they did, and they explained the technitians pleasure at finding it and how he found it. They are all really into making cars safe and operating properly, as well as appreciating various vehicle benifits. Great Job!
