New and used 2025 INFINITI QX80 SUVs for sale near Lake St. Louis, MO

This was my 1st time taking my car to this location and they were very nice and professional. Service was done in a timely manner.

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.

This is my fifth infinity and by far the best car I?ve owned three of my Infiniti purchases. I picked up the car. Two of the online purchases were shipped to the appearance of the dealership this ranks 2 out of 10. very little contact with the sales manager the salesman was very friendly and tried, but his knowledge of the car was average. The business manager wasted a lot of my time and overall we are total buying experience was below average. I?m going to put down that I would recommend this dealer to a friend but with the caveat that buyer beware and needs to check what he?s getting.

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.

My experience at Plaza Infiniti was exceptional. Ron did a fantastic job during the process. Ensuring that I got what I wanted. He listened and delivered!

It was refreshing and nice experience. I dropped off my vehicle in the evening and the next morning I got a text about the progress of my vehicle. I appreciated the quickness of letting me know that they were working my car. Later on that afternoon, I get text about my car, letting me know what was critcal and what was recommeded. The text included video of the problems, you cant get any more transparent than that about your car issues! There was no presssue and my car got done quickly. When I went in to get my vehicle, Morgan was great in letting me know about the situation with my car.I told her that I was a veteran, and she told me they military discount! Saved me money and my car is running like a top! You can't beat Quality care and they helped me with bill with military discount! I will go to them for EVERYTHING...oil changes or anything else. Waiting room had complimentary drinks, coffee and snacks. The customer service was FANTASTIC!

Buying process was smooth sailing, Ron made the car shopping experience very easy and less stressful Very knowledgeable Would purchase another vehicle at Plaza Infinity Motors if needed
