Walked in. Was not greeted. Waiting for the service advisor I was told I had an appointment with. He decided to call someone about their extended warranty rathe Was not greeted. Waiting for the service advisor I was told I had an appointment with. He decided to call someone about their extended warranty rather than check me in even when I was standing in front of him. Upon pick up, no inspection was covered with me. Just a $100 oil change and tire rotation, pay and have a nice day. Will never return here. Only great part of the service was the porter who brought my truck back. Had a dodger hat on, shook my hand and told me to have a great day. More

Avo Injian handled my visit and provided an absolutely outstanding customer experience fr maintenance, auto repair, and a manufacturer recall notice. Avo Injian handled my visit and provided an absolutely outstanding customer experience from start to finish. From the moment I arrived, Avo was incredibly attentive to my needs and made me feel like a valued customer. He took the time to explain the entire repair and recall process in great detail, ensuring I understood exactly what work would be performed on my vehicle. What stood out most was his exceptional commitment to communication. Avo kept me informed with consistent updates throughout the day, so I never had to wonder about the status of my vehicle. His professionalism, transparency, and dedication to customer satisfaction turned what could have been a stressful repair visit into a seamless, positive experience. I highly commend Avo for his excellent work and top-tier service! More
