Very disappointed that Sterling McCall doesn't honor the $49.95 price they advertise on their website. This is the second time this has happened. Why even advertise if they don't honor.

Great experience, highly recommended
While I'm a little tardy on sharing my buying experience at Mac Haik, I can tell you I'm very happy with every aspect of it. Purchased/ordered a new Ford truck over the phone, dealt with Lawrence Gallegos at Mac Haik, easy to work with. Provided me with a great deal, great customer service and made sure everything was exactly as we talked about, even making sure the delivery was accomplished very professionally which included arranging transportation. Many thanks to Mac Haik and Lawrence for making my purchase a pleasure. Highly recommend this dealership

I bought a car from this dealer entirely online, and their team went above and beyond to assist me. They helped with the inspection and even took the car to the dealership for a recall, and this happened to be for a BMW. Despite the transaction being online, they provided exceptional service by personally handling these tasks for me. I?ve already sent them both thank you's, but still their effort truly exceeded my expectations. I?ll definitely return to them for my next car purchase.

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.

I recently bought a 2014 BMW X5 from Hue - he was very attentive and helpful. I had a 3rd party inspection completed prior to purchasing and they gave good marks for the car. I have received many compliments on how new the car looks despite being over 10 years old. The owner, Kal, offered top-dollar for our trade-in and even offered us fair money for an older car. The purchase process went very smoothly with Trice, and the dealership was very responsive when I needed some help with a trailer hitch. Their collection of cars impressed me - they seem to only sell cars in excellent condition. I can definitely recommend America’s Auto Financial to anyone looking for a nicely used car!

Immediate response. Made an appointment to see the vehicle. Unfortunately, it sold before I arrived. However, the salesman did not make me drive over an hour to get there to find out it was gone. He called and texted to save me the trip. Really appreciate his respect of my time.
