Great service, smooth process. I found the vehicle I wanted at a great price. Everyone was very friendly. I will certainly consider Grand Prairie for future purchases.

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!

My wife and I bought a 2021 kickehs with very low miles from them. I am in my 50's and was the best buying experience that I ever had! The quote for the vehicle and the monthly payment didn't change a penny throughout the process, other words no baiting just to get you there. Very honest pain-free experience! My daughter is next in line for a car and we will definitely go straight there for our purchase!
2021 GMC Sierra Denali
This is the nicest truck I have ever owned. Lots of features. Takes a while to learn what all it does but a really enjoyable vehicle.

They truly deliver excellence in both cars and customer care!

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!

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.

Family. That's the feeling you get at every step of the purchase process. From Victor, our salesman who kept us at least two steps ahead to Cesar in Finance who finished the deal, we were treated as family. I have not experienced such a smooth and painless purchase in a very long time. Trophy Nissan and it's staff deserve a standing ovation.

Reggie was outstanding. Anything that could happen he handled it. He made every sure everything was smooth and I was comfortable. 100/10 He made sure that we were taken care of. Even when the dealership was closed he made sure that we didn't have any problems and everything was good. Made us feel like royalty honestly. I would recommend Reggie to anyone he handles business and makes sure the buyer is comfortable.
