I have a lot of bad luck with cars, so when I saw my check engine light on I wasn't surprised but super nervous. I took my car to Aamco, and they checked it and it resulted it was a false alarm! My car was fine and they reset my light, it was the best news I have received in a long time- until they told me they weren't going to charge me a thing.
Now THAT is service, and made my entire week. :)
