New and used 2026 Cadillac CT5 for sale near Columbia, IL

Found the car with the mileage we'd been looking for. Drove from Tallahassee, FL. to Ocala, FL. and Sullivan's to trade our existing car in on the 2019 Mercedes. In and out in just over 2hours. Gotta be a record for buying a car. Sullivan's was very efficient and professional. Highly recommend them for your next vehicle.

The CT 5 Sport is a hot ride. It’s loaded with all the bells and whistles, from Supercruise assist to the hottest styling of the dash, it’s truly phenomenal! The change between touring and sport is seemless, there are so much to say about this car and not enough room!

There were absolutely the best company to work with Pedro to selves men was through the roof Nick the sales manager could meet a nicer guy would totally recommend a dealership 150%

Coulter dealerships have been very good to me with the vehicles I have bought from them in the past. Coulter Cadillac was the best experience yet. I got a great deal and I know it! The deal was mostly done on line and did not change the day the xt6 was picked up. This is not the usual dealership experience. No wonder Coulter has been around for 100 years. Thank you very much, Steve and Nancy

The young lady was extremely attentive and helpful. I haven't purchased yet but I'd purchase with Crest.

Friendly courteous dealership with interest in your personal satisfaction. Fair pricing and finance terms to suit your budget. Overall good purchase experience.

I contacted Luther Cadillac thru Cars.com. A representative contacted me within a few mins but I changed my mind about the car and didn't have any more contact with this dealer.

Sean and Jackson were awesome. Most honest and straightforward team that I have dealt with all my years leasing cars. In my case they went above and beyond expectations, even to the point of providing a greater discount than what was agreed upon because of an incentive issue. I would not hesitate to contact them if you are considering a new vehicle!

I wrote a review a couple of days ago, but have since worked with Cadillac to resolve this issue and while it will not let me edit the last review I can post a new one. Working with service centers can sometimes be very challenging, especially as a woman that does not know very much about cars. It's essential to me that I am able to go to a place that I know I can trust. In February of 2022 I took my car to this dealership to get a new key fob after losing one and have my transmission inspected. My car was under an extended warranty and they were able to replace the transmission control solenoid and get both of my new key fobs under warranty and at the end of the day it only cost me $46! Along the way Tim Radice, my service consultant was absolutely phenomenal. He kept me updated and made countless calls to my different warranty companies to ensure I was spending as little out of pocket as possible. Within a week I had my car back. Sadly shortly after my transmission started acting up again and the problem was much worse. I took it back to the dealership and found out that the transmission cover had warped and it was going to be a $1,500 fix because my warranty had just expired. Tim did everything he could (he's awesome like that) and put me into contact with the service manager, Paul. From the moment I got on the phone with Paul I could tell he was handling this with the upmost professionalism. He was kind and patient and he let me spend 10 minutes walking him through the initial repair to my cars current state. Paul quickly jumped into action and got on the phone with GM to figure out why this was happening. He called me back after speaking with GM Engineering and let me know that there was some critical information GM had not relayed to them. Apparently any time you replace the solenoid you need to replace the cover as well, because it disrupts the seal and often causes transmission fluid leakage. Paul said they would 100% cover the cost of labor and asked if I would cover the $149 part, saving me over $1,000. So if course I said yes! They had no LEGAL responsibility to offer me this, especially given that they had no way to know this information at the time of the initial repair. It is; however, the right thing to do given that the issue stemmed from the initial repair. I am so thankful that Paul, Tim and the other Cadillac team members did their best to take care of me in this situation. Car troubles are never fun and are almost always quite costly. It's worth it to go to a place you can trust - and this is it.

I purchased a 2025 Ct4 Luxury from Delaware Cadillac in July 2025. I noticed some inconsistencies in the paint on the passenger rear quarter panel and the rear parking sensors were working intermittently. I contacted Tony in the service department, and she checked the problems I had. She scheduled an appointment with the paint service and had the parking sensors checked. The day I came in for the scheduled service, Mike checked my Ct4 again to make sure he saw the problems too be corrected. I was given a Ct4 to drive while the work was being done on my vehicle, this was helpful because its the same car and I did not have to figure anything out. Mike called and told me that the paint was worked on but he did not think it was any better than I had done with the touch up and the parking sensors were checked and seemed to be as they were supposed to be. When I arrived to pick up my vehicle, I was very happy with the paint work and the vehicle was clean as I left it. It is important to me that some one knows that I am very satisfied with the way this issue was handled . I want give kudos to Dane Tjaden for sales, Mike Anderson and Toni Spille for service. Thank you, I have never been treated this well by a car dealer. ( Cadillacs are more than a car!) T. A. Olin To Whom It May Concern, I purchased a 2025 CT4 Luxury from Delaware Cadillac in July 2025. Shortly after, I noticed some inconsistencies in the paint on the passenger rear quarter panel and found that the rear parking sensors were working intermittently. I reached out to Toni Spille in the service department, who promptly scheduled an appointment to address both concerns. When I arrived for the service, Mike Anderson inspected my CT4 again to confirm the issues and ensure everything would be addressed properly. I was provided with a loaner CT4, which I greatly appreciated—it made the transition seamless since it was the same model I’m familiar with. Mike later contacted me to provide an update. He informed me that while the paint had been retouched, he personally didn’t feel it was much of an improvement over my own previous touch-up. He also noted that the parking sensors were tested and found to be operating as expected. However, when I picked up my vehicle, I was genuinely pleased with the paint work—it looked much better than I anticipated. The vehicle was also returned to me clean and in great condition, exactly as I had left it. I want to express my sincere gratitude for the excellent customer service I received. It’s important to me that someone knows how satisfied I am with how this situation was handled. I’d like to especially recognize Dane Tjaden in sales, and both Mike Anderson and Toni Spille in service. Their professionalism, transparency, and care made all the difference. Thank you again. I have never been treated this well by a car dealer—and I firmly believe that Cadillacs are more than just a car! Sincerely, T. A. Olin

They were very professional, courteous and cared about what you want in a vehicle, without the hard sell. They answered all my questions and the quality of service was great. They even did follow-up to see how everything was going and needs from them that might be required.

Bryan Skipper is always helpful and great to deal with. Great experience and recommend him as your service advisor. Facility is clean and nice waiting area.
