Overall experience was great. I was impressed with the safety details Adrean provided. Those details helped me make a better decision regarding fixing my car. Although I still hear that quiet thump, I will take a closer look at the trunk of the car as it could be something I am carrying in the trunk or possibly my spare tire. Again, overall it was a very good experience. NAPA - You guys continue to excel in the service that you provide. It helps your customers feel good about driving their car and being safe. Thank you.
