New and used 2026 Cadillac CT5 Premium Luxury for sale near Festus, MO

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

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!

The staff were very nice and polite and kept me informed. The waiting area was very comfortable. The facility is very clean and modern. Thank you!

Great service! I felt welcomed and at ease. The staff were very friendly and I didn’t feel pressured to buy!

I was very fortunate to have the greatest salesman, manger, General manager and finance director in the business assist in my purchase. Thank you "Coach" for all you do for me and the family

Had a small issue but they took care of me. Picked my vehicle up from my place of employment and brought it back to me.

We had a great experience. Scott Johnson was our salesman and was absolutely terrific. We also had great interactions with the Sales Manager and the Finance Department. Would highly recommend them to anyone looking for a new car!!

Great service and sales support after purchase. Left us know approximate time replacing antennae would take and kept us up to date with progress. Our sales person left us use his personal vehicle to run around town with. Could not have expected better...

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.

Best service I’ve ever had. Tyler Sullivan was very helpful and made sure my Cadillac is running like new. Thank you.

Avia is perfect professional. She was very patient with us and made the process very easy. A+ service. She goes beyond. I hope to do business again.

GOOD RAPOR WITH ALL CONTACTS THUS FAR, ALSO GOOD INFORMATION PROVIDED. PLAN TO STOP AT THIS LOCATION TO VIEW THE BLACKWING/S.

Great experience, Antoine Richardson was my sales associate and immediately assisted me over phone with a Jeep I have been eyeing for sometime. He worked out some numbers before my long drive but it was well worth it. Very good person, took me for test drive and spoke like we knew each other. Meet the finance manager and she awesome as well, just pretty cool experience. Would buy again from the dealership!!!

Excellent interaction and service with Jennifer in Warwick. Thank you! I appreciated the service provided yesterday.

I am a new customer to the Johnson auto group, and after my experience will certainly be a returning customer. The sales staff, specifically Shelby, was amazing. They were attentive, fair, reasonable, and transparent throughout the entire process. I am so happy I decided to purchase from Johnson GMC. Ultimately, I left the dealership with a new truck and a great experience where I felt that I was a valued customer and that my business was truly appreciated.

I enjoyed working with Mr. Watkins. He was professional and kind. He always made sure I was comfortable. Mr. Devon did the paperwork and he was no pressure. Overall I got what I needed and asked for. Makes me think I should have asked for more!! lol I am totally satisfied.

Response by Josh was quick. Answered all my questions and sent additional pictures that I requested.

Jake is both professional and personable. He deserves a five star rating. He was easy to work with.

The oil change and tire rotation service went well. I have always taken my vehicle to get the oil changed since I made the purchased from Ross Downing. Great service and very professional.
