Bought 2 Cars Here, Now Going Back
Bought a car here. After several years I traded it in and bought another. Values were fair on my trade-ins. Vehicles on the website are really the ones they have on the lot. No pressure, no negotiating, huge selection. Paperwork process like normal. I did have to refinance after I left there because the interest rates were steep and I got better deal from credit union. Overall recommend. Had a car accident, will return to Carmax.

My experience at this dealership was great!
My experience at this dealership was great! Garret was my salesperson and he was very experienced and did a great job helping with my car purchase. He gave me the keys and I knew it was the one. I test drove the car and it drove perfectly. The tires looked pretty new and the inside had no damage. The cars on their lot are very clean and maintained. Sam was who I worked with on the financing and he was very thorough in explaining all the options that I had. All the people there that I met were very nice and friendly. I would definitely recommend this car dealership.
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!

Fast, Friendly, and Helpful
I saw a 2014 Silverado LTZ that had all the features I had been looking for. I set my mind to drive up and look at the truck (I opted not to transfer as I had family in the area I intended to visit). The hold process is GREAT. It's a quick click and I knew the vehicle was going to be there after I drove the 3 hours to look at it. I worked with Chris Biggs and he was great. We talked options on the truck and for financing (they beat my credit union's offer). He was incredibly friendly to be around and my wife and I thoroughly enjoyed talking to him as we waited on our financing offers. He was thorough in making sure we had all the facts and options. If I had anyone in the area looking to buy, I would send them to Chris in a heartbeat. Then I know they'd have a good experience and be completely taken care of.

First time customer in Dallas, Tx
For some reason Mark's name is not on the list where it says, "Choose their name," but Mark was so helpful, patient, explained the process clearly and was very professional. I highly recommend him and would work with him and his team again. I would hope for a promotion for him Hyundai. :)
