AutoNation Ford in Arlington set me up with the Maverick
AutoNation Ford in Arlington set me up with the Maverick pickup I was looking for: color, features, engine, everything. Holden was the BEST salesperson I have worked with. This is the second vehicle I have purchased with him and AutoNation Arlington.
This truck has a jerk when changing gears sometimes.

Fast service and very professional
I bought a year old BMW. The price was better than I found at other dealerships. They were prepared to go as slow as I wanted and answer all my questions, but that's not what I wanted. I wanted fast! So after a quick test drive went in and signed the paperwork, while they washed it for me. They let me leave my old car there and drive my new car home. There was a headlight malfunction and they said it was completely covered under warranty. However, because it was a software issue, Carmax said I needed to take it to BMW, but that Carmax would cover any costs. They were true to their word!
Nicest, best performing truck I've ever owned
My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

No pressure No games Easy buy of a cash car.
I went to buy a cash car. I had a price range to follow. I looked at a Lexus 07 LS460. I was helped out in getting a deal for this car by Jesse. I had some some request to be addressed first, to make me feel better about the deal. I saw they where all made. Maybe not to a high standard but they were done. The whole process felt easy with no pressure. I never believed Jesse was playing games with me. Ever. All in all he sold me a car I wanted and at the price I wanted. What more can you ask for? It's a 07. It's got issues. Yes. It's a used car but the buying experience was never an issue. Would I go back to buy another one? Yes. Will I tell a friend? Yes. I just recommend you do your own research on the particular car your looking at. I did not and still got a good deal. Ask for Jesse.

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.

Great deal, easy experience! 10/10 would recommend
Great buying experience! Small town, local dealer that made the process super simple. I dealt with Jesus in sales who had my new truck pulled up and ready to go when I got to the store. I was in and out with my new truck in less than an hour!

Automobile purchase at the Hiley Hyundai Burleson
From the moment arriving at the Hiley Hyundai Dealership (Burleson), we were greeted with smiles and courtesy. I noticed the facility had been remodeled since my last vist; super nicely done. The process was seamless and clear which was indeed appreciated. Brad Fansler was our Sales Person/Manager during the process; very accommodating. Our vehicle purchase options was to our liking as we were intent with our preferences; again very pleased with the process. The finance process was clear, effortless, and prompt; quite please with that part of the process. Furthermore, the closing moments of the overall process proved to be the reason for our preference to shop for vehicles at this dealership; we've purchased three automobiles from this Hiley Dealership, and will continue to do so for these very reasons.

Easy, Efficient, and Friendly Place
I purchase a used vehicle from Post, and was blown away! After shopping around for quite some time, I arrived at Post and loved everything about it. The process was simple and smooth, and we were able to agree on a price before I even arrived. I would highly recommend Post if you're looking to purchase from a small dealer, that very much embodies the people of Texas!

The salesman, Jason, was courteous, knowledgeable and low
The salesman, Jason, was courteous, knowledgeable and low pressure. We literally bought the car (2014 Mazda 3 I Sport) in only a little over an hour, including the test drive. No high pressure tactics nor “upselling”. I highly recommend Cransh as well as Jason B.

Best Car Buying Experience Ever!!
Jose the Sales Manager listened to what I wanted and found the vehicle at another dealership and brought it over. Briana in Sales showed me all the features and explained how everything works. She even helped me get the app set up on my phone. David in Finance was so friendly and made the process easy. I have told all my friends how nice everybody was to me and this was really a no-stress day. I love them. I wish I could buy a new vehicle every year so I can go back over and over.
