New and used 2025 INFINITI QX80 SUVs for sale near Glenn Heights, TX

While traveling with my family, after thousands of miles, we decided to have a review of our car. So we found this dealer. The experience compare with other INFINITI services dealers I have been, was very good, efficient and honest attention.

This SUV is incredible. It's very quick, quiet, and it's extremely comfortable. Combine that with the best looking exterior in its class and the fact that it's 10x better than the previous model and it's a winner.

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!

Was greeting the moment I drove in. Definitely good Customer service they were able to turn a bad situation to a good experience. John and Ezekiel were very helpful in getting my car in to get worked on. Will definitely be coming back

I LOVE the Grubbs dealership. They always take such good care of my car and make things go smoothly when it's in the shop. I had quite a bit of work done this time and I couldn't be happier with the outcome! Chas Velarde was one of the most outstanding service advisors I have ever worked with. He really listened to my concerns and he has such a wonderful attitude. The entire staff, from the front desk, to the attendants who bring your car to you, are always so nice to deal with. I feel lucky to have bought my car from Grubbs and will always bring my car, that I love, to them for service.

Isaac Marquez was my salesman. This young man was very attentive to my wants in a new car. He found the perfect vehicle for me. I met several of his team members and they were all wonderful. I will recommend this dealership and Isaac to all my family and friends. Thank you, Grubbs Infiniti.
