VERY knowledgeable guys, with the highest level of knowledge, service and warranty I have found outside of a dealership. I went to a shop nearer to my house initially, and which was cheaper, and they could not solve the issue I was having. Charged me twice, too, including parts I didn’t need. Car Doctor was able to address the issue correctly, which the other shop and even AutoZone (AutoZone read an incorrect code) were not able to do.
