Advance and Autozone are the mc'ds of auto parts.If the parts guy knows anything about cars he would smart up and move up to a dealership or a better parts job.I remember when i worked there 5 years ago i had STORE MANAGERS call me from other stores asking me technical questions.A store manager at advance/autozone/pepboys makes what i make and i still sell parts and have no "manager" responsibilities.I quit with no notice and have never regretted it.Whenever i go to advance i start looking up OWN parts and tell them to i used to run a store so they can back the fuck up.I usually just give them the part number so mistakes arent made.
