Used INFINITI cars for sale near Sidney, MT

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.

After spending time with the 2024 QX80 Sensory, I’m comfortable giving it a five‑star rating—not because it’s perfect, but because of how well it delivers on the things that actually matter in this segment, especially at the cheaper real‑world transaction prices these typically sell for. The build quality stands out immediately. Material quality, fit, and finish are all genuinely impressive, and even after 30,000 miles the cabin remains tight with very few creaks or rattles. That’s something I can’t say about several other luxury brands I’ve owned, including BMW, Mercedes, and Cadillac, which tend to develop interior noises far earlier. On the road, the QX80 excels at what it’s built for. The ride is extremely comfortable, highway noise is well controlled, and the 400‑hp V8 provides smooth, effortless power. It’s a relaxed, confident cruiser that makes long family trips easy. The interior is spacious, the leather is high‑quality, and both the interior and exterior design have a clean, upscale look. Fuel economy is average for a large V8 SUV—nothing surprising there. The real drawbacks come from the dated technology. The infotainment system feels behind the times, and features like a head‑up display or massaging seats simply aren’t available. The front seats could also use more side bolstering for better support. Even with those shortcomings, the overall package is strong. When you factor in the typical selling price—often well below MSRP—the value becomes even clearer. You’re getting a large, comfortable, powerful, and well‑built luxury SUV that prioritizes reliability and long‑term durability over chasing trends. It’s not perfect, but nothing in this class is. What the QX80 does, it does exceptionally well, and that’s why it earns a full five stars from me.

Jessie was a wonderful and nice salesman made sure I left satisfied and happy the experience with Jessie was the best i've experienced in a long time.

The Sensory trim model offers excellent amenities and comfort options. A very quiet and smooth ride not lacking of power. The electronics are simple to learn and easy to use.

Julian was a great experience and very helpful liked working with him and his management

So far I'm in Love with the Car. Comfortable Tight Vehicle. I gave the Cadillac Escalade a try for years and they just simply disappointed me . QX80 is a winner.

Purchased a new Avalon from them today. Wesley Radford was my sales rep and the entire process was an extremely pleasant experience. Wesley was patient with me and did not give any hard sell tactics. There was a slight glitch due to my misreading some info and Wesley rectified everything to my great satisfaction. Everyone else in the process was polite and helpful. Lombard Toyota is the place to go and Wesley is the guy to ask for.

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!

I live in California and while visiting my daughter in Fort Worth my 2011 FX50s broke down needing a starter. I called the Infiniti dealership in Dallas which was close and they told me that they may not work on it because of its age. I contacted Grubbs Infiniti in Grapevine and they immediately told me that they will fix it so I can drive back to California. They did exceptional work and and the service manager was attentive to any questions or concerns I had I recommend Grubbs and super satisfied with the work done on my 2011 FX50s.

The I talk with was very Profession And knew what He was talking about, very Focus., smart guy

Quickest car buying experience I have had! Always ask for Lathario to get your car needs

I had a great experience buying my 2019 Infiniti QX50. The entire process was smooth, stress-free, and straightforward from start to finish. The salesman David was knowledgeable, patient, and never pushy—he took the time to answer all my questions and made sure I felt comfortable with every step of the purchase. He really went above and beyond to make sure I found the right car and left happy. If you’re looking for someone who’s honest, professional, and easy to work with, I highly recommend him. I’m absolutely loving my QX50!

Vehicle meets and exceeds expectations. Very quiet, virtually maintenance free with the exception of the passenger side seat heater. We are working with our Dealer to resolve.

Randell the Service Adviser is Top Notch and did an outstanding job. Will use him in the future for all service work on our Audi.

I have a 2023 brand new off show room floor an my windshield has been leaking water from outside when it rains extremely hard outside had to take it back within 1 month of having it an they kept it for 70 + they replaced the windshield only for it to happen this year again this is not a good look for infiniti the service department say my car is the 5th car to have issues with water leaking from windshield

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.

Ricky ,Shawndy , Alan , The Best Customer Service Team they actually Care they go that extra Mile to help you . And the Lady Technician Quisa is very helpful. Thank you

We were very pleased with our experience. Don was very quick to return my initial communication. He explained the procedure for us meeting and had the car ready for our examination. All care was taken to insure the cleanliness and contamination free condition of the car. The procedure for purchasing the car was smooth and followed social distancing standards. We could not be any happier with how we were treated.

It’s a great car however I do not feel like “things are conveniently “ located. When driving, I struggle with finding the defroster, or adjusting the entertainment system. Perhaps with more time, I will get used to it.

I had a service appt for software recall on my new Qx80 at the Naples Inifiniti. The day before my appt I found out the dealership was closing that day. I call Infiniti Fort Myers to see if I could get an appt. (Even though it was almost hour from my home with traffic) The person who answered and scheduled my service was so nice I knew right away I was going to happy with this dealership. When I arrived the two men who checked in my suv were so friendly. Jenna my service advisor was so very nice. she was able to provide me with a loaner with no problem. Which was really nice experience then my experiences with naples Inifiniti. She kept me up to date on the progress of my suv . I look forward to Infiniti fort Myers bring the deal ship that services my car.

Great experience! Very responsive and professional. Great customer service, nice dealership and really good deals.

I usually work with Andres and he is absolutely fabulous at his job! He tries to really take care of Eid you and you vehicle.

I recently purchased a 2025 Infiniti QX80 at an excellent price. Even at full price, it offers good value in the full-size luxury SUV market. After one month, here's my assessment. Strengths **Styling**: The QX80 features elegant exterior and interior design that outshines most competitors. The Navigator's redesign was disappointing, while the Wagoneer lacks refinement. Only the Escalade matches its presence, though with a more aggressive look. **Value**: Infiniti's current market position creates pricing advantages. Feature-for-feature, the QX80 is thousands less than competitors across all trims. **Powertrain**: The twin-turbo 3.5L V6 delivers smooth power through a 9-speed transmission. I'm averaging 20-21 mpg in mixed driving (better than EPA estimates), though it requires premium fuel. **Comfort**: Ride quality and noise isolation are excellent for a body-on-frame vehicle. The air suspension mitigates most harshness from the 22" wheels. **Handling**: It drives more like a midsize SUV, handling mountain roads with unexpected confidence. Only the pricier Escalade V offers better dynamics. **Space**: Dimensions match standard Navigator and Escalade while exceeding the Lexus LX. The third row comfortably fits adults with easy access, and cargo space is generous, especially with seats folded. **Towing**: All models can tow 8,500 pounds, above segment average. Only Wagoneer models with Hemi V8s offer more. Weaknesses **No Homelink**: Inexplicably lacks the standard garage door opener system. Instead uses "myQ," requiring compatible equipment and Wi-Fi. It works roughly 20% of the time for closing, 50% for opening. **Missing Trailer Brake Controller**: Despite strong towing capacity and pre-wiring, it lacks this essential safety feature that the cheaper Nissan Armada includes standard. **No Rear Sunshades**: A premium family vehicle should include this feature, common in less expensive SUVs. **Limited Storage**: Few interior storage options beyond a modest console and small pass-through. The Autograph trim's "cool box" reduces console space by half while offering minimal functionality. **Software Issues**: I've experienced two significant electronic failures already. Once, the infotainment rebooted while driving. More concerning, at 1,200 miles, the dashboard, HVAC, and air suspension failed simultaneously—a potentially dangerous situation. Uncertain Factors **Reliability**: Infiniti typically outperforms Nissan, and Japanese production suggests quality. The VR-series engine appears promising, but competitors have documented issues too. Air suspension systems generally develop problems after several years. **Resale**: Likely below Lexus but competitive with Navigator and slightly below Escalade. Verdict I'm satisfied with my purchase, especially given local dealership availability and favorable pricing. The electronic issues create some concern for long-term ownership. For shoppers prioritizing style, value, and driving dynamics who can accept some feature omissions, the QX80 deserves consideration in this competitive segment.

Dave P the salesman was very easy to work with and he really understood what I wanted. He aslo went out of his way to pick up a document I forgot. Great guy.

Very nice truck. Only thing missing is massage seats and better fuel mileage with Premium fuel. Otherwise, I love it as it is still makes heads turn.

Our experience was very transparent and up-front. We were treated with respect. The new (to us) vehicle was in perfect condition. We enjoyed the process.

Amazing customer service. Kaden and Latesha are extremely knowledgeable, thoughtful, thorough, and refreshingly professional. Their attention to detail and consideration for me as a buyer made my experience pleasant. They answered all my questions and covered things I didn’t consider. I asked the hard questions, and they responded with ease. They didn’t rush my decision. They were patient (even as the sun was setting). They sealed the deal! If you’re looking to purchase a vehicle, start with Kaden and finish with Latesha. The Dynamic Duo!
