New and used 2026 INFINITI QX80 for sale near Prosper, TX

I am on my 4th Sewell Infinity. Great sales experience every time and Service is the best (compared to some other high end dealerships in Dallas)

The best way I can describe this dealership from both sales and service is to say that it is the way customer service should be done. The values placed on the consumer is something both old world in terms of respect, and new world in terms of how to manage the experience and maintain long term relationships with their consumer. My vehicle was bought used and needed service six months after purchase. I must commend both the service writer Jessiel Cortez and the service manager Krista Polito for their professionalism and kindness above all expectations. I am immensely happy with my decision to both buy my vehicle from Sewell, and trust their service department to manage my automotive experience. To put it simply: I don’t know why anyone would go anywhere else for a car.

Very professional group of people. They did a great job of contacting me and following up. Sent me all the info I needed for the vehicle I was interested in.

Response received from the dealership was very quick. Everyone at Sewell Infiniti was friendly and attentive all of our inquiries. Vehicle was exactly as displayed in pictures and great purchase experience completed in 2 hours!

Awesome experience!! My wife and I were treated with respect and kindness. They are definitely everything their commercials say they are!

We purchased a QX60, and really loved the sales, finance and sales management staff at Crest Infiniti in Frisco. This is our second new car purchase from them in four years-they keep us coming back!

The staff was friendly, patient and knowledgeable. Overall the facility is quite nice. Everything we were told before we even arrived was accurate and no gotcha's or pressure at all.. Highly recommended as it was a very nice experience.

My Advisor, Robert Moler is exceptional in his role on the service team . Robert is very knowledgeable about the vehicle, and always provides complete detail on any question I may have about my QX60!! Robert is very professional, and goes above, and beyond to take care of your vehicle needs.

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!

Their service department is simply first class, Trou Dunn was service consultant and he did a remarkable job getting our rather unusual problem with out Infinit solved.
