These guys were able to troubleshoot and fix an electrical problem I had been living with for more than a year on my 03 Dodge Ram 2500, and very quickly. They took into account the troubleshooting work and parts replacement I had already done, were very communicative throughout the process, and charged me a very reasonable price. I plan to go to By the Book for all my future auto repair needs, and I highly recommend you do too! - Matthew
