The service that Golden Wrench provided was amazing to say the least. From calling in my request to showing up, the operator/owner of the business was very personable and knowledgeable, and understood that my time is very valuable. In total It was 10 minutes from dropping off my car to having it passed smog and them having it pulled up so I could pay and leave. Professional, speedy, and very friendly — all of those traits means I will be a return customer for most if not all of my engine needs. Highly recommend!
