Cadillac hit a home run with the CT6
Love the style, ride and the ease to learn the technology. Very happy with getting premium performance using regular gas. Plenty of room for all 5 passengers.

The nice thing about working with this dealership was we were able to negotiate everything over the phone and that way we could go pick up the car and everything was prepared and ready and we were in and out of there in no time
Beautiful and comfortable car
It is easy to navigate , good for gas, quiet but still shows the work of the engine. Warms up quickly and has luxurious look.

The service was wonderful!
The service was wonderful! My wife and I worked with Arman who was super helpful and knowledgeable about both vehicles we purchased. We purchased two pre-owned vehicles. The vehicles were in great condition and they gave us a reasonable price for our trade in. I would highly recommend them!
Car size is good, considering the market for sedan
Plenty of room. I used the controls on the steering wheel. Never on console, sometimes on screen. Seldom take eyes off road. Had twenty months left on my XTS bumper to bumper . Next car was going to be CT6. I don't know what Cadillac is doing with sedans. There were no CT6 in Tampa had to go to West Palm but the CT4 and 5 were too small. The screen on the CT5 looked like it was slapped on top of dash and sun roof left something to be desired. Cadillac and sedan?????. looks like Electric in the future ?????

Great value
Almost all options are included in a specified trim level so purchasing is straightforward. “Infotainment Center” has an overwhelming combination of great GPS navigation, electronics inter-connectivity, communications, and entertainment features. Enhanced safety features are impressive, from notices (visual and tactile) of cross-traffic backing out of driveway, to blind-spot warnings, following-distance display, etc.

Emillie Y from Minnesota
I highly recommend Bergstrom Cadillac of Madison. They guided me in the right direction when I needed a reliable vehicle for not only myself, but my newborn as well. Their upfront pricing made the entire car buying process incredibly easy. Not only did Seth and Kyle listen to my requests but they made helpful suggestions. They showed great communication and knowledge when answering all of my questions. In fact, everyone who I encountered was professional and polite. I left the dealership more informed and satisfied with my purchase. I will definitely purchase my next vehicle from here. Thanks again, guys!
Standard of the world
I’ve owned a wide variety of cars, Maserati, Mercedes and BMW. I always go back to Cadillac. The quality is top shelf. Interior design is way better then the Germans, especially BMW which I feel is the most hyped car in the world. The ride in my CT6 is comfortable but not floaty. It gets good pickup fro the 335 hp V6, but I feel a V8 option other then the Blackwing would be nice. I hope Cadillac comes out with a full size replacement for the CT6 by the time I’m ready for a new one.

I purchased a 2025 Ct4 Luxury from Delaware Cadillac in
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

Our experience with Mackenzie and Sewell could not have
Our experience with Mackenzie and Sewell could not have been better. She replied promptly, answered all our questions and concerns quickly and professionally. We were purchasing from Virginia and ordering a car from Texas was a daunting prospect but the employees we dealt with at Sewell were absolutely amazing. There were no hidden fees, they were transparent about small cosmetic flaws we would never have see in pictures but since we couldn’t be there in person she sent us videos walking around the car showing every detail. Small flaws were repaired for us before the car shipped. Literally, the car is better than we could have hoped for! We are so thankful for the way Sewell treated us and would highly recommend Mackenzie and her team. 5 star experience!

Members were very receptive and helpful in my journey
Members were very receptive and helpful in my journey into buying my first Corvette. Every member was available to answer questions even when my primary contact was out of office, presenting a collaborative (not cutthroat) team sales approach. The dealership was extremely clean and presentable. Its status as a leading Corvette dealer provided ample on-site cars that give customers an opportunity to see a variety of different options in-person, which drastically helped with decision making.

Rizza GMCCadillac see Coach
We walked in looking for a new or lightly used Cadillac. Coach Novak approached us and was absolutely fantastic. He was right he isnt a typical salesperson. He wasnt the typical slick talking, fastmoving stereotypical sales guy. He was respectful of my wife and my time and our needs. We got an great deal on a beautiful Cadillac. Thanks Rizza and Coach for all your service and attention in our new purchase.

I bought a 2018 Nissan pro x a little over a year ago.
I bought a 2018 Nissan pro x a little over a year ago. I drove from ny to look at it it was clean except for front bumper was hit in corner and paint was scraped. They repaired the damage perfectly by the time I picked it up. I was impressed by their professionalism. The only thing that I thought was a little extravagant was the dealer fee. We negotiated a fair price and now it’s mine. I’ve had the vehicle for over a year and it is flawless. I felt I needed time to make a fair judgement of the vehicle before my review. I would not hesitate to buy another vehicle from thi dealership
