We were on vacation at Sunset Beach, NC, when my car began sputtering and the check engine light came on (It's a 2002 Mazda). The closest shop to us was NAPA, and I'm glad we went there. They ran it up on the diagnostic machine, and they told us that they couldn't repair it, but it would hold out until we got home. They printed the findings out so that I could bring it to my local dealership when we got back. They were very friendly and helpful, which is unlike most places back here in CT.
