This is the second time I have had a vehicle worked on by 521 Automotive. I have been completely satisfied with both experiences. The last visit was concerning an engine light that had come on. The truck had started running rough and I also noticed oil leaks underneath the engine. Bill diagnosed the engine codes and provided an estimate for repair. My son and I had questions concerning the listed repairs which were happily answered by Bill. We trusted his abilities and diagnoses to repair the truck properly and professionally , which it was. The truck starts and runs great, and no oil leaks. The price was very reasonable, considering all the work it took to replace multiple gaskets it needed. Great job Bill. Thank you.
