Used INFINITI QX80 for sale near Frontenac, MO

My salesman Aaron Voege was excellent,courteous and I will recommend him to all my friends.. He made the transition from my Altima to my new Rogue perfect. Thank you Aaron..

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.

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.

We had the best experience with Autocenters Nissan. Our salesman Nikolas Kennedy was amazing. He worked with us to get the best possible deal that worked for us. We love our new Nissan Frontier ❤️ We highly recommend Autocenters Nissan 😊 Robert Smith

This is my second Infiniti. I still own my 1st one which presently has 312,500 plus mile. It was very reliable. I wanted a vehicle that had everything I wanted in it. So, I purchased it. I love it is all I can say.

Arman is always amazing! Great at explaining service needs and planning for the next! I always feel welcome at Audi, the facility is top quality and I am so glad I purchased a car here!

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 Sinclair is awesome, my only complaint - I didn't receive my complimentary car wash.

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.

I bought my car at Napleton Nissan in 2018, and I’ve been coming to them for my oil change, tire rotation, and maintenance since. Everyone is very nice and very helpful. They explain things very well. I won’t go anywhere else.

Our salesperson was knowledgeable about the process and vehicle, courteous and overall very helpful. I would recommend him to anyone who is thinking about purchasing a new or used vehicle.

I spoke with Tra Farrow recently at the Alton IL. Location. I was completely honest with him. He ask where I was thinking I wanted my payment to be monthly. I give him my response. I was buying a pre owned vehicle. I bought a Dodge Ram regular cab. He also was completely honest, respectful, of my request. He said he would see what he could do. After talking it was clear that we could complete the sale. I have always purchased my vehicles from private owners. This is the first time I used a dealership. I have this dealership and Tray a five star rating. While I realize it is difficult to get it give a business a five star rating. It was easy to give them the best possible rating. Everyone whom I came into contact with during my visit was outstanding. I was overwhelmed at how easy it was. This business could not have done anymore to change my opinion of dealerships. I know all things do not end this way. If you are in the area of Alton IL. Please give Tra and the staff an opportunity to serve you.

I am so pleased with this truck and this is the 3rd one that I have purchased from this same dealership. The staff really went far and beyond to find me the exact model that I want.

Kelly is awesome helped me trade my xxx for an amazing truck. Love it thanks

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.

Mark Eversgerd was great to work with no pressure ,this is the second vehicle that I have purchased from Mark and I didn’t have to spend the whole day at dealership.

I met with Dave Fisher, he made me feel very comfortable from the beginning all the way through the whole process of buying a used vehicle. No pressure, no stress. I was very happy I decided to go to Sapaugh GM Country. Thanks Dave for making the process and easy one

I bought the car recently. I would recommend if you want a nice interior and don't need all of the fancy tech that are in the newer rivals. I like the off road capability as we drive on the beach a lot and occasionally have to drive on some tougher trails. The comfort is really good though not quite as good as the new GMC Yukon Denali with the air suspension. The interior is reasonably plush but not as nice as the Navigator. It is just a step above the new Expedition or on par with the Yukon Denali. The main reason I bought the QX80 was for its off road capability. We have already done some moderate off roading and it performed flawlessly. The power is adequate. Not fast, but plenty for almost everyone. The only complaints are that the transmission is a bit lacking on gears.

Came in for a repair on my vehicle and was also getting a rental the rental department went above and beyond to make sure the vehicle was clean and disinfected and ready for me I was in and out of there in no time at all will definitely be back because of those young gentlemen.

Josh Roseke was very accommodating, professional and accurate. He ensured the experience was painless and efficient. The dealership should be proud to employ an associate of his caliber.

Drove nissans and Toyota my whole life..I was looking for an armada but got the luxury version instead which is the QX80. Very luxurious in and out my only gripe was the infotainment which is severely outdated with no android auto or Apple car play. still this big girl has plenty of power and the V8 is intoxicating lol which I'm loving. THIS truck isn't meant for fuel economy, if you want that, get a hybrid. Very reliable and luxurious. Hermosa Blue is plainly gorgeous for this truck.

I bought a 22 Ford Bronco from Clement Ford in December 22 and have had on scheduled service which went great using the valet service they provide. However, what really impressed me was this week I had an issue with the bead locks on my wheels. I spoke to Jerry and Alex in their service department and they were able remove the bolts I was having issues with, allowed me to use the valet service once again, and didn't even charge me for the time. I'm very happy with my experience with them so far!

I came to this car from a 2016 Yukon which was a rolling dumpster fire. At 102k miles, I haven’t had a single failure with this car. It tows extremely well, the seat comfort is by far the best I’ve ever owned, I don’t love the exterior styling, but its such a great owner experience that it doesn’t matter. Maintenance is like owning a Camry, cheap and infrequent. AWD system makes driving in all conditions a breeze. Great vehicle.

I always have excellent customer service when I bring my car in. The technician found two items that needed to get fixed. I was able to pick my car up the next day.

Brett was able to locate a hard to find vehicle for me at a great price. No hassles.

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.

The car buying process with Plaza Infiniti was amazing through the whole process. They were very accommodating with the whole process, even when purchasing from out-of-state. Barney makes you feel at peace with the selection process, and Rob is very knowledgeable and helps you to find the best deal when it comes to financials. Altogether was an amazing experience and I would recommend Plaza Infiniti to anyone looking for a new car.

Anthony just sold me my fourth car great effortless seamless great personality makes you feel right at home visit Plaza Infiniti and ask for Anthony Jones. You won?t regret it.!!!

Alan Oldham and Jimmy Dolan helped us get our perfect car. From the color, to the options to the price. It could not have gone better. I will send everyone their way. I cannot remember the man that helped with my paperwork, but he and everyone involved was professional and could answer every question.
