I was originally quoted over $600 to replace a battery and alternator, neither of which I've had for very long. My alternator was still under warranty, so I brought them a new one and they installed it. My final price was a tad over $200. After they replaced the alternator, they tested the battery again and said I didn't need a new one after all, a fact that impressed me greatly considering how easy it would have been for them to charge me for something I didn't need. I'll be taking my other car there later today.
