I had an amazing experience working with Trevor when purchasing my Ford Explorer Platinum! From start to finish, he made the entire process smooth, stress-free, and enjoyable. Trevor was incredibly knowledgeable, patient, and honest ? he took the time to answer all my questions and made sure I was completely comfortable with my decision. He went above and beyond to find exactly what I wanted and made sure I got the best deal possible. I couldn?t be happier with my new SUV and the top-notch service I received. If you?re looking to buy a vehicle, I highly recommend asking for Trevor ? he truly delivers five-star service!

Ozzie and Belinda took great care of us.
Ozzie and Belinda took great care of us. 1. We had to trade in a car that was costing too much to repair. I put the information into the Echo Park system and Belinda called to ask further questions. It was that outreach that had us going to Echo Park instead of CarMax. 2. Ozzie was the salesperson who happened to be free when we walked in. He listened to what we wanted to do and made a couple of good suggestions. Then one test drive and we were ready to buy. The dealership honored the trade-in value and even added $250 to it, and altogether that helped pay for the warranty that we purchased.

My wife, son, and I had a wonderful experience. H�ctor, who assisted us throughout the process, was extremely kind and professional. He showed us the vehicle options we were looking for and worked to get the monthly payment as close as possible to our budget. There was absolutely no pressure to buy at any moment, and he was patient while we made our final decision. We definitely recommend him to family and friends who are looking to purchase a vehicle.
