Iliana was a great sales rep.
Iliana was a great sales rep. She was kind and very understanding of what I needed. She acquired to my needs and didn’t make me feel pressure to make any decisions until I was ready. 10/10 experience with Iliana Davila.
So far so good!
So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

Forest, our sales representative was an amazing man.
Forest, our sales representative was an amazing man. He was very professional and knowledgeable. He was also very friendly and went out if his way to make sure we knew all about the vehicle we were interested in purchasing. He went with us so I could test drive the car and explained all the features and how to work them . Forest even took me around the dealership and introduced me to various employees, showed me where the service and parts departments were and, once again introduced me to the people in those departments. He also showed me where the customer lounge and vending area was along with the free coffee area. Forest introduced me to the finance person who would be serving me. On a scale of 1 to 10, I would rate Forest a 12. Outstanding! Thank you Forest, Ralph Larry Malone

Excellent experience at Classic Dodge Arlington
I was in the market for a new vehicle but dreaded going to a dealership. It is like knowing you need to put on boxing gloves and go 12 rounds and try not to get beat up too bad. Classic Dodge had the exact truck I wanted so I called and talked to Alonzo Contreras. From that first call he was honest, easy to talk to and no high pressure at all. He is awesome and I highly recommend him. Yissell Medina also worked with me and did a great job. Last but not least, Jeff Miller in the Finance office was the best I’ve ever dealt with. He explained everything in plain English, did not try to strong arm me and left me feeling like he honestly wanted to get me the best deal possible. Good Job Classic Dodge!
