Found the car with the mileage we'd been looking for.
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.
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.

Gary’s the man!
Gary’s the man! Walked me through the process and delivered as promised. Keep up the amazing work!!
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 service as usual.
Great service as usual. I have been a customer for 10 years here and have always been satisfied weather I'm buying a vehicle or having a service done.
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.

Dropped my vehicle of for service.
It will take a week to get your car looked at because they are so busy, but they fixed my truck quickly and properly with daily updates. Great service. And I highly recommend buying the 2-3 year warrenty. I'm very very thankful I did.
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 just wanted to say thank you to Faye in sales and James
I just wanted to say thank you to Faye in sales and James in finance. This was probably the easiest and least stressful car buying experience I have ever had. I’m always on the defense when dealing with car sales people. That’s why I usually like Carvana. But they do not sell new cars, and you technically can’t drive them or look at them before signing on the dotted line. Faye and James didn’t hard sell me up front or in the back office. Faye and James are credit to the industry, and I thank you for restoring my faith and giving me a great buying experience. Now I’m going to try their service department soon. Buyer of 2024 CPO Kia Sportage PHEV!

The part for our tail lamp needed to be ordered, so we were not scheduled for the repair for about a week. However, when the part came in, they made arrangements to get our vehicle fixed the next day. The shop waiting area was clean and coffee/tea was provided for us waiting on repairs.

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

Kevin Brown at Courtesy Cadillac would rate >10 stars if they were available. He was very professional and knowledgeable about my SRX's mechanics. He kept me informed, when he could, since the dealership is VERY busy! At the end, Kevin made sure to provide me with everything I had asked for. I appreciate his kind words of advice on how to best maintain my 2015 SRX, which is in pristene condition, but I do need to drive it more;) Thank you Courtesy Cadillac for Kevin Brown, he is a treasure, like Matt Gardner in Sales.

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.

We purchased a 2022 Chevrolet Malibu in February 2025. Our sales rep was Izzo Ramos. He took great care of us right from the start! He asked what we were looking for and showed us some cars that fit our preferences. He listened to what we were looking for and we felt comfortable with him. Izzo made car shopping a nice experience at Empire Hyundai in Swansea Mass! We thank Izzo and Empire Hyundai, for our wonderful car!
