Used INFINITI cars for sale near Valley Park, MO

Jeff Reed provided great service. He is attentive to what we want to know and goes the extra step to make sure he provides that. All the people we spoke to were professional and friendly.

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.

Ron, and the entire staff are first class! My wife and I flew down from Minneapolis. Ron picked us up at the airport. We took the vehicle for ride & within an hour and a half, we were on our way home. The smoothest transaction I've ever had buying a vehicle.

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.

This is the 3rd vehicle I have purchased and currently leasing a new vehicle from Sapaugh. Rich Konold is the best sales consultant. He knows the vehicles and can help you match your wants/needs to the best vehicle for you, and get you the lowest price.

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.

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.

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.

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

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.

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.!!!

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.

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

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.

Very good car so far with more amenities than I knew rides well with great acceleration and gas mileage. There are blind spots that’s take getting use to. Love it

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.

This rig is tight and comfortable as xxxx. It drives tight and handles like it is nobody's business. Yea it does not have remote start and navigation system. I just have to get a 2019 Infiniti pure base that is. I did not pay attention about those amenities. It is not a big loss. You can get a navigation sysem for nothing. And remote start in the winter time I suppose can a be a great thing to have. As you can warm up your car before hand. I guess it is not the end of the world. But the rest this behicle is cat's meow.

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

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!

We went in to have our tires rotated .Everyone was very friendly and courteous.Was very impressed with the fast customer service.Thank you..

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.

Wonderful thank you Fred Willams and team for the amazing experience ❤️❤️,Im so greatful you guys are wonderful

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 felt they were honest 1st of all. Can't say that about very many dealerships. They gave the best trade-in value on my 2015 Tahoe (by far). I searched Missouri and Illinois for about 8 weeks and Sapaugh was the best experience Hands-Down. My ONLY fault with my whole experience was getting my paper work finished. It was a cash deal with a trade-in. NO financing needed. But it was a holiday weekend (01/02/2026) only one guy doing the paperwork processing instead of two. NOT a giant deal.

Hello there. This is my first time driving a twin-turbo vehicle. I must say, I am quite impressed with the power and performance of this car. It feels similar to the power of my previous vehicles, a 2020 PP2 5.0 Premium and a 2022 5.0 Premium with 460 horsepower. The all-wheel drive launches are particularly enjoyable, and the car handles nimbly in traffic. I appreciate the spacious and comfortable interior of the Q50. It feels like a luxurious living room, and the 16-speaker Bose sound system provides beautiful and clear sound. I often find myself sitting in the car just to listen to music. Overall, I am very pleased with the Infiniti Q50. It is a powerful, comfortable, and enjoyable car to drive. I am glad I finally decided to purchase one, and I do not think I will ever part with it. Well done, Infiniti!

I had an excellent experience working with Rodney Brown. From the very beginning he was knowledgeable, attentive, and genuinely interested in helping me find the right truck. He provided clear, honest recommendations, and I never felt pressured to make a purchase.

The car has the same engine as the Nissan 370z and is actually faster in a straight line even though it was 2 extra seats. Has an amazing exhaust sound and you can get a bit of wheel spin out of the car with it's 330 horsepower and 270 lb-ft of torque. Overall it's a luxurious, fun, and quick car with aftermarket potential if you're into that.

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!!!

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 the body design, the interior is comfortable. However the technology could be more updated. Car is very reliable it does 26 GPM on the highway, engine is very powerful.

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.

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.
