DealerRater Sep 10, 2026

Chelsea is reliable and communicative, tech maintenance staff not reliable, new damages after repairs, vehicle back in service for new damages after just a couple of days out from service, issues in the past with customer service by an agent named Oscar. He’s no longer there. Management had contacted us from previous service issues, promised some kind of compensation never heard back, which I’m not looking for a handout I’m looking for reliable service.

DealerRater Sep 10, 2026

Great experience took time to explain everything and make sure we left with a car.

DealerRater Sep 10, 2026

Took 3 hours for a $200 oil change with an appointment. I waited at the dealership and they failed to notify me when the car was finished even after I asked. It's almost like they made me wait on purpose.
