The law does require that your Ford Mustang be repaired either at a certfied smog check repair facility or by the owner of the vehicle, personally. The main reason for this law is to protect the consumer.
When smog check repairs are made by a non-smog check certifed mechanic the State will not support (investigate) any problems which may arise due to improper repairs or any disputes. Having your Ford Mustang repaired at a certified smog test repair center will allow you to contact and get support from the BAR (Bureau of Automotive Repairs) should the need arise.
