Used INFINITI SUVs for sale near St. Charles, MO

Craig Shattuck was amazing for the 2nd time. Bought a titan in 2017 and now a 2026 frontier. Go see Craig

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.

They had vehicle we were looking for. Very good at assuring we had a good experience.

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.

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.

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.

Taking a 12-year-old CTS Sport Wagon to a Cadilllac dealership for service tends to make one brace oneself for the onslaught of potential sales pitch that naturally occurs when an older model comes in for service and the dealership is in the business of selling brand new ones. To my pleasant surprise the approach was quite the opposite and Terry, along with members of the sales staff, all seemed genuinely happy to provide service work without the sales pitch. The work was completed quickly and the car remains the reliable and fun-to-drive car that has been a testament to the make's time-honored claim as "Standard of the World". Even when I mentioned that a new Cadillac might be in the cards someday, the staff was happy to know they were helping keep one of the most iconic models that Cadillac has produced in recent years on the road. Thank you, Terry and the staff who worked diligently to get my car repaired and back to me well within the time frame that had been promised.

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.

Best salesforce of any dealership that I have ever worked with. They met all my needs and I love my MKZ

I've had this vehicle for 2 years and I love it. Such a smooth ride for a large SUV. Beautiful on the outside and inside. No mechanical issues whatsoever so far and i'm at 90k miles

Jamie was the best, would send anyone to him...very knowledgeable, attentive, and relaxed through the entire process. We will seek him out in the future and send friends.

Bought this vehicle for my use. Out beloved Tahoe come up with a check engine light and we decided not to spend money on an older vehicle. Our DIL did some searching and found this one for us to check out. It looked like it came off the showroom floor. Even it was 5 years old it was immaculate and the maintenance records were maintained. I’m so impressed. In my seventies I feel like I’m driving a sports car. So much different that driving the large SUV but still has a third row of seats when needed and plenty of room for luggage and/or packages. Couldn’t be happier. Even my husband will use it instead of driving his Dodge Ram.

I had a great experiencing purchasing my car from BMW of West St. Louis. Dawn D. is an excellent person to work with. My purchase was remote and she acted as my eyes and ears, providing a trustworthy assessment of the vehicle I selected as if it were her own. She answered questions, made a video and was readily available to answer questions leading up to and through the purchasing process. The shipping process was seamless with a fast turnaround time. Armin H. was great on the purchasing side of the process. Extremely detailed and clear on cost, warranties, etc. All around great team to work with!

One of the smoothest running cars I’ve ever driven. Smart styling and easy handling. Has all the features, amenities and upscale options ones finds distinctive and comfortable. Infiniti did a good job o this one.

Blaine was very professional and helped us buy our new car. Thanks, Blaine for everything!

James and all of the folks we dealt with were great, professional, and so helpful with helping us understand our car, financing options, etc. We LOVE our EV9!!!

My Name is Gayle McClure, 1st I’ve been taking my car to Sunstrup over 10 years. The technicians and service advisor, Ian, and Scott are the most knowledgeable and patient people with their customers. I trust their advice, they always tell me the truth. I would recommend anyone who ask me to trust Sunstrup.

Is good reliable luxury car.Little expensive on gas as is need premium and in city 16.4 gallon/100miles.Perhaps not suitable for daily driving to work?Unless you don’t count every penny.

Salesperson Fred Williams did a fantastic job with assisting and selling me a JAG! If you need a volvo or any other car used or new, see Brother F. Williams.

I purchased this car last year I can say it is best car I ever owned, it is true the interior not like German but, when you drive it you forget about interior since i purchased no issue I drove 3000 miles monthly it is made for motorway comfortable with high tourqe offer strong performence I prefer qx70 over bmw and, mercedes

I was interested in test driving a Nissan Kicks . We were assisted by Mason who was very helpful and knowledgeable . He explained everything to us about the vehicle. A lot of the things were so new to me since I had been driving a 2009 vehicle. We enjoyed working with him and everything went smoothly with the purchase. Thanks again to Mason Nash on our purchase .

Love it!!! My salesman Ali Abdullah at Infiniti in Clarendon Hills. He was very patient, helpful, understanding with our needs. He made this experience exciting and comforting! Please ask for him, he will take care of you. Joe is amazing as well!

Tommy was very helpful and had prompt communication. He followed up and provided additional photos of vehicle.

This particular car meets all my needs. Leather seats common FM/a.m., heated seats, Sunroof, three USB ports just completely fully loaded. Is a keeper no doubt. Completely satisfied

The process of negotiating the purchase of a vehicle was relatively painless. Salesman was not pushy and easy to talk to.Never felt pressured into buying.

It was a great experience! The salesman, Josh, was very knowledgeable and provided our family excellent service!

I just recently purchased this car. I can say I’m pretty satisfied. It is pretty luxurious and smooth. I’m a happy customer. Would definitely recommend this car to my family members

Bought it used 2 years ago. Fun to drive. More of a sports car than a SUV. Great for single ppl but not a family car. Unique style. Big ppl barely fit in it though. Tons of power thanks to the turbo. Stands out in the crowd

I had the absolute best experience at AutoNation in St. Peters, MO. My salesperson, Anthony Smith, was upfront, knowledgeable, patient, and kind throughout the entire process. He never pushed me into anything—he made sure I was comfortable at every step and even gave me helpful tips on what to look for during a test drive. I later learned Anthony is somewhat of a local celebrity here in St. Louis, and it’s easy to see why. His approach and personality made the whole experience authentic and enjoyable. I also want to recognize Nate, the sales manager, who worked hard on my behalf to lock in the best deal for my situation. He truly went above and beyond to make sure everything lined up in my favor. And finally, Cameron in finance made the paperwork side of things stress-free. He explained warranties and add-ons so clearly that there was no need for pressure—the way he laid everything out spoke for itself. Because of his clarity, I was able to confidently choose what mattered most to me without feeling pushed. Altogether, this was hands-down the best car-buying experience I’ve ever had at a used car dealership. Anthony, Nate, and Cameron earned my trust, and I won’t hesitate to follow Anthony wherever he goes when I’m ready for another vehicle.
