I found this database to be mostly helpful. The contact information for the majority of the listed auto parts shops was accurate and up-to-date. However, I did encounter a few entries with outdated or incorrect phone numbers, and a handful of businesses that seemed to be listed incorrectly. Overall, it saved me a considerable amount of time in my research, but a little more rigorous verification would improve its value. I'd recommend it as a starting point, but plan on doing some double-checking.
