Affiliates & Certifications
AAA Approved Auto Repair
All AAA members receive a 10% discount on parts and labor charges up to $50.00. AAA approves less than 5% of all automobile repair shops in Southern California. That is because most auto repair shops cannot hold up to the scrutiny their investigation and inspections demand. AAA looks into our credentials, our equipment, our technicians’ abilities and certifications, and they even check with the state to see if we have violations or complaints on record. We are subject to surprise inspections from AAA representatives and graded on a multitude of categories. Associated Automotive Service maintains AAA expectations and is proud we have their approval.
ASE Certified Technicians

We employ ASE certified technicians and are diligent about keeping up with the latest technology by consistently attending new training classes and seminars to stay in tune with the ever-changing automotive industry. Associated Automotive Service is your one-stop maintenance shop to help you maintain your investment in your vehicle.
Financing Available


When costly car repairs happen unexpectedly that don’t fit into your budget, it can be hard to get the repairs done. We understand that so we have partnered with Napa’s Car Care One credit program. The application is short and if you meet the requirements, approval is immediate. The best part about this credit card is that it offers deferred interest financing options available. Ask us about it.
