New and used 2026 INFINITI QX80 for sale near St. Charles, IL

Had some noise taking in the front of my car. I’m already at 90,000 miles on my 2021QX 80 that I just purchased January. Turns out that’s the repairs were covered underneath the eight year unlimited mileage warranty that I bought is the time of purchase. These guys are great. Never feel pressure on buying any extra Which is why I keep coming back. Every four years I get about 450,000 miles on my vehicles because I travel cross country and they keep me moving and the warranty lets me sleep easy at night. Thanks guys.

I had a great experience at this dealership, i had the courtesy of having Ali Abdullah as my dealer and he was extremely patient, understanding, and helpful in my purchase of my vehicle!

Excellent! Staff was courteous, friendly, and knowledgeable. It was a very pleasant experience. I will definitely check the inventory before buying my next vehicle. Well worth the drive.

Alec went above and beyond to make a deal work, no hard sell, easy to work with,

Alec Olney is the best salesman! He helped get my mom into a car she loves and he made the process so fast and streamlined!

Tyler was incredibly knowledgeable while assisting me with my search. I can't thank him enough for the time and patience he gave me. If all sales staff at INFINITI Hoffman Estates are like Tyler, I would highly recommend this dealership to anyone interested in purchasing a vehicle.

Chris was so responsive and helpful! He made everything seamless and simple every step of the way. Highly reccomend!

Great Experience, answered all the questions, showed and explained everything I wanted to know. Very nice experience.

Great guys great deal. Andrew and Dale took good care of us. Thank you. We’ll be back

I bought a car from them this week and was very satisfied and impressed. I highly recommend salesman Christian Fernandez - he was very professional and made the process personal, comfortable and fun! He provided exceptional service. If possible call ahead for an appointment and come prepared, I'm from out of town Christian helped me get it all done in 1 trip, trade-in and all.

Fantastic experience all around. Magdalena was very knowledgeable about the car I was interested in and was instrumental in guiding me through the process. The entire experience was smooth, friendly and professional. Joseph was a delight to work with in finance and he was patient and knowledgeable in working me through that process. There is a reason I have been coming to Infiniti of Naperville for years, and it is because of their team members. Buying a car is stressful enough, but it truly helps to have partners in the process who understand and appreciate my needs and work hard and collaboratively to meet them. Most importantly, Magda and Joseph are great people and I enjoyed hearing about why they are passionate about what they do. Just a great experience all around.

Wendy was my sales person and she was the most sweetest person ever. Gave me a great deal!

Had a very pleasant experience with Matt Webber and Dave Pearson at the Dealership. Matt was very good with the financing portion and Dave was a very positive person for the purchase. I would recommend going to the dealer and ask for these two Managers.

I’m not much of one for writing reviews, but in the case of Infiniti of Naperville, the extraordinary and impeccable service and attention they have recently provided me must be acknowledged. Short story – I needed to have them replace the engine in my Nissan Maxima. Jon Vargas, my service rep, arranged to get an engine delivered to the dealership within the next couple of days, and then have it installed and the car ready no later than Saturday just before I was to leave on vacation on Sunday morning with my daughter for a week. Saturday came and as promised the car was ready. I picked it up, and on the way home from running a few errands, the Check Engine light came on. At first I figured it might just be a “nuisance” sensor fault, and thought it’d be OK. But once home, without going into details, more severe symptoms arose - the car would no longer start, all kinds of error messages were appearing! I texted Jon in a panic, not sure what to do as I was leaving on vacation the next morning, and the dealership was now closed. In response, Jon said he’d come right over (and also had his lead tech come over) - they drove over to my house (after their working hours – they were “off the clock”!) and personally spent 2+ hours trying to diagnose and fix the issue. Unfortunately, they could not restore functionality. At this point I’m scurrying around trying to arrange a last minute rental car that I could pick up Sunday morning (at a potential cost of $600), but Jon was having none of that. After a flurry of phone calls to the owner/general manager, they arranged for me to be able to pick up a loaner car at the dealership on Sunday AM. Not only that, Jon came and picked me up Sunday morning at 7:30 to take me to the dealership, where in short order I was able to get a loaner and be on my way on vacation an hour later. So this was a long story, but it serves to demonstrate what I feel is, in my experience, unmatched customer service. They made a promise that my car would be ready, and available for my upcoming vacation. When through no fault of their own it wasn’t, they did EVERTYTHING to make it right – coming over to my house when they were not “on the job” and had no obligation to do so, opening up the dealership on Sunday morning to provide me with a loaner vehicle, ferrying me there. These are simply extraordinary measures that demonstrate the ultimate in customer service. It would have been so easy for them to simply blow me off and say “we’re closed, have the vehicle towed here Monday morning”, and probably most dealerships would have. But not Infiniti of Naperville – the folks are the salt of the earth. I’ll never go anywhere else again.
