Very good and courteous staff.
Very good and courteous staff. Had difficulty locating my appointment but all went smoothly afterwards. Picked up my car in no time. It is always washed for me!
Short turn radius
I purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.

Great car buying experience
We were very pleased with our experience. Don was very quick to return my initial communication. He explained the procedure for us meeting and had the car ready for our examination. All care was taken to insure the cleanliness and contamination free condition of the car. The procedure for purchasing the car was smooth and followed social distancing standards. We could not be any happier with how we were treated.
Great Truck
I did my research and test drove several models. The GMC 1500 Duramax does everything I want it to do and more. Great gas milage, nice power and very comfortable.

I have nothing but good things to say about my experience
I have nothing but good things to say about my experience with Auto Merchants. Christian Lopez was my salesman and he was great to work with. He gave me a great deal on my car and the buying process was so quick and easy.
Best truck I’ve bought
The features and styling are very aesthetic. The truck has very smooth handling and response. I am impressed with the response from the Diesel engine.

Excellent experience throughout
I have now been to this facility twice in the last two years (once to get an appraisal for a vehicle I ended up selling myself and now (Sept/2018) for a used vehicle purchase. Both times great, but this most recent was a shockingly easy process throughout with a very good person (Greg Leo) from CarMax. I had a specific need and the car was in CA (I am in TX) and Greg set up delivery, responded to any request I had, and kept me informed at all times of the stages. When I met him for actual purchase, I was in and out of the process (including a trade in) in 2 hours (prob could have done less but we got along well). This IS the way car buying should be done! Period. Great people, great business model. I also used CarMax financing with zero issues (excellent credit) and there is no pressure involved whatsoever (it is built into their process).

Fantastic experience.
Even in these trying times they made the whole experience easy and painless. From our sales agent Trent to the financial guru Brian, everyone was friendly and helpful. They are 96 miles from us and I would not hesitate to make the trip again if they have something I want. We'll worth the trip.

We had a straightforward, no hassle, seamless car buying
We had a straightforward, no hassle, seamless car buying experience at Ewing. Our salesman, Clayton, made the entire process easy for us from trading in our ?problem vehicle? to finding us the exact car we were looking for and having it delivered promptly. There were no salesman tricks, no hidden fees and no pushes to purchase extras we didn?t need. All around great experience. Highly recommend!
