Used INFINITI cars for sale near O'Fallon, IL

Working with Trent and the staff at Dave Mungenast was easier than I had imagined. While looking at vehicles all day, we were exhausted and ready to give up. Finally, after visiting many car dealerships, we found one at Dave Mungenast. Thank you Trent and staff that stayed after hours to help us finalize our purchase.

Very friendly and courteous staff. Kurt was great about explaining the features that the truck has to offer.

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

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.

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.

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

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.

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.

Great experience. Kayden was great. No pressure at all to buy . I will tell all my friends to come here

A big shout out to Carlos Holmes, Newbold BMW Technical Support. He did an outstanding job ensuring our profiles were complete. This allowed us to manage our app’s properly and to drive our new high tech SUV. He was exceptionally patient with two tech challenged senior citizens. Thank you Carlos, you were great!

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.

Rick is one of the best around. He takes great care of his customers and makes the process quick and easy. Thanks Rick!

Owned this car for over 10 years and had 0 issues. Great family car that will fit 3 car seats across the middle seat. So much leg room for older kids as well and was a top selling feature. Numerous bells and whistles that are similar to newer cars like lane departure, blind spot and 360 camera view.

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.

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.

Very good service and friendly sale Very good service and friendly sale force to work with.I enjoyed the process of purchasing new vehicle thanks Bruno he real deal 🤞🏽🥳

The lease on our car was up and a friend recommended Suntrup in South County. Since we were up that way we decided to check it out and were greeted by Zach Seiler at the door and we’re pleasantly surprised by his knowledge, patience, and low pressure salesmanship. In a relatively short time we were transferring items from our old car into our new 2021 Volkswagen Jetta-which we really did not plan to purchase that day. And by the way Zach helped us with that, too

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.

Cory Reno helped us buy our cars. We just bought our sixth car from Cory on Saturday. He is very knowledgeable and easy to work with. Highly recommend him!

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!

Everyone at the dealership was amazing! They answered all of my questions, made me feel comfortable, and confident with everything! I definitely recommend this dealership to anyone looking for a used or new car.

Drives and handles very well on the road. The only surprise was during purchase. I expected it to have a Bose sound system like my G35 had, and the automatic front seat and steering column. On my G35 these two systems moved in unison and had memory for the position of the seat and steering column that could be set for two different drivers. The only other thing is the absence of a spare tire. Those run flat tires ride very hard and are not cost effective for owners.

I recently had the pleasure of purchasing a car from Suntrup Kia South, and I can’t express how satisfied I am with the experience. Despite being a thousand miles away, their professionalism, transparency, and warmth made me feel right at home. From the moment I connected with Moe Saad, I knew I was in good hands. Moe exemplified the epitome of a top-notch car salesman, providing me with reassurance and guidance every step of the way. My search for the perfect EV9 led me to many dealerships, but none matched the integrity and authenticity of Suntrup Kia South. Moe and his team went above and beyond, offering red carpet treatment without the need for an actual red carpet. Even while under the weather, Moe ensured a seamless transaction, passing the baton to Dzenis, who continued the stellar customer service. From start to finish, every detail was meticulously handled, including a thoughtful conversation with sales manager Dave, who ensured my satisfaction was met at every turn. In an industry often plagued by deceit and gimmicks, Suntrup Kia South stands out as a beacon of honesty and excellence. It’s rare to find such a level of service and transparency, and I can confidently say this was the best car-buying experience I’ve ever had. Despite the distance, I’d make the journey again without hesitation. If you’re in the market for an EV9 or any vehicle, do yourself a favor and visit Suntrup Kia South. You won’t be disappointed. Hats off to Moe, Dzenis, Dave, and the entire team for exceeding expectations and setting the bar high for customer satisfaction.

Weber is an excellent place to purchase a car. This is my second purchase with them. My sales person Tony Franks, provided outstanding service, he was very professional, personable, and knowledgeable regarding the product.

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!

So far i have never had a problem with this car. I love my car, its the best. It has different drive modes like sports standard etc. It also drives very good in snow. I also get great miles to the gallon.

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.!!!

If you looking to purchase a vehicle and want great customer service, knowledge about cars, and really listen and care about what the customer want please visit Infiniti of Clarendon Hill and see Ali Abdullah. You won't go wrong!!! I walked away with another Infiniti.

Awesome experience at 111. Easy process and got in and out with a car at a cheap price in no time.

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
