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.

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
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.

Good costumer service and very helpful it was what we expected plus they have nice cars
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 ?????

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.
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.

Everyone who helped me was really great and helpful. I would recommend this dealership to who ever wants to buy a Ford. They are very knowledgeable.
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.

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.

This is my first car, and I’m happy I chose the Advantage
This is my first car, and I’m happy I chose the Advantage Acura of Naperville dealership. Not only was the inventory impressive, but so were the professionalism, consideration, and promptness of the sales consultant I worked with, Le Roy Churchill III. My family has trusted this dealership for years, and I’m proud to continue that relationship. Not only were my needs and wants for a vehicle thoroughly considered—including the quality of the car, its previous upkeep, and fair pricing—but every explanation, question, and detail about the car was addressed with honesty, transparency, and a clear focus on my best interests. Overall, a wonderful experience.

Great Experience overall!
Great Experience overall!! I recently bought a 2025 Infiniti QX60 from this dealership. Overall a fantastic experience. Trevor made the entire purchase a seamless experience. Dave the GM went above and beyond to make sure I got the SUV I was looking for and that everything was exactly as I hoped it would be. They both followed up with me after the purchase to make sure everything was taken care of. The owner Greg also reached out during the buying process to make sure his team were taking great care of me. Overall it was a great experience. I got the car I wanted and the entire team were great. I'd definitely recommend them!

After all day car shopping around town, we ended up at
After all day car shopping around town, we ended up at the Continental Toyota 45 min before closing. It did not matter, we received the same great service from Michael P. - "Let's go for a test drive!", "Let me answer all your questions!", "Let me crack a joke", "Lets talk to Finance", "Let me go to Services and find out the answer for you"- He was always willing to help and to find answers of our new used car. Eventhough we were ALL exhausted from car shopping, Mike made it at ease. A week later we needed to return and take advantage of our Silver warranty. Stephan was our guy. He was also willing to go beyond to ensure we had a car that was perfect for us. Frequently, calls were made to me to make sure I had what I needed and double check the car was running smoothly. After a few trips to the dealership, CJ (manager) also took care of us for certain incoveniences we had - after all car shopping is not like buying a piece of gum. :( Thank you so much for your patience with us. Overall experience: Very satisfied with Continental Toyota, not to mention the cleanliness of the place and little treats available while you wait or do some "work from home" in the shop :))

Overall The salesperson John was most helpful, kind and professional. My only complaint was it took them a while to get all my paperwork and docs that I signed emailed to me. Also car shipment company they used to transport vehicle to my destination could have better up to date info on delivery date... instead of last minute.
