My AC was working at less than optimal cooling, which I discovered on a trip. The small town where I was visiting family did not work on hybrids so I called CARS and got an appointment to bring car in when I returned. When I signed in on Monday morning, I was given an estimate of approximately $65.00 and was told i would be called when they found out what was going on. Around 4:30 pm, I called to inquire and was told they thought it might be a leak and car would be ready by 5:00 so I headed over. I was very surprised to find out charge was $204.00 for the work, since I had received no call to say what was going to be done. This is very unusual in my experience with this company; a month earlier when I had my car in for a thorough check over, I was called with the estimates for proposed work and I okayed it and when I picked it up, charge was exactly what I'd been quoted verbally. I, of course, expect to pay for work done but it would be nice to have some forewarning about costs.
