Chris Calltharp did an excellent job finding us the
Chris Calltharp did an excellent job finding us the perfect luxury suv, a QX 60. We visited many other dealerships to look at an explorer, pathfinder, blazer, rx350, Range Rover, Toyota and some used suvs at Carmax. I was not really impressed with anyone else’s knowledge or simple honesty. I applaud Chris for ensuring that this was a positive experience for my wife. She is extremely happy with her new 60! It was a pleasant experience. Please go find Chris and give him a chance to get you into an Infiniti. Sam in finance made that portion a seamless transaction as well. Very happy with Crest Infiniti!
Great Buy!
This truck is amazing. Turning heads all over as we tour the area. Those riding with is also enjoy the comforts and safety features. Great Buy!

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.

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.

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!

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.
