Used INFINITI QX80 for sale near Plainview, TN

This is my second Cadillac from Mike and Cadillac of Knoxville. Special ordered a new XT4 and I am very pleased. Mike as always is professional, courteous and knowledgeable. I would recommend Mike for your next Cadillac purchase.

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.

We would like to thank Trent and Kayla for their outstanding customer service during our shopping and car buying experience. They were both very courteous, knowledgeable and communication during the entire process was quick and easy. They made everything seamless and enjoyable. We will definitely recommend these 2 great associates and West Chevrolet to everyone we know! Thanks again for the professionalism displayed by this dealership! We drove out of our area to purchase a car from there and the time spent was well worth it!!!

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.

Harper Infiniti - Knoxville Exceptional Care and Customer Service from Sales to Service to Finance to Matt, the GM This Team over delivers!! Five Star 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.

Everything went smoothly. Got the car I wanted. Nice facilites, not in a small cramped trailer or rundown building. Absolutely would recommend them.

Had first service done on my GMC HD. I was taken in on my schedule appointment with no wait time. Truck was serviced quickly. Will be returning to them again.

Comfort, power, space, looks - the Infiniti GX80 has it all for my family. We needed space and we got it. Infiniti added style and comfort. I'm very happy with this vehicle - both on the highway and around town.

Easiest car buying adventure we have ever had. Super friendly staff. Will buy here again in the future. Customer service is there focus, unlike some other dealeeships we went to.

Harper Infiniti is a joy to use. Their service and attention to detail continues to impress. I often find they have added something extra at no additional charge to either their service area or waiting room. I live almost 60 miles away and can have my QX-60 serviced at Harper less expensively than in my hometown.

I have had 4 infinity vehicles, 3 purchased at harpers. Sales and especially service has been a pleasure to deal with. I want to single out Eric liner for going above what is expected to help me with any problem I have.

One of the best car buying experiences I have had. Rosemarie was fantastic to work with and provided all the information I needed including a personal video of the vehicle. The team at Harper gave me a fair price on my trade in and the sales process was extremely fast and efficient. Highly recommended for your next new or used car, they are a class act.

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.

The process was easy, the workers were great. It wasn?t a headache at all. I would definitely buy from them again and would recommend them to anyone.

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.

Walter Hoover-our sales person was very knowledgeable, which made our experience purchasing a new 2023 Lexus GX 460 easy and fast. I highly recommend Walter Hoover and Lexus of Knoxville.
