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.
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.

Incredible Service & Sales Departments.
Incredible Service & Sales Departments. I've purchased my last 2 vehicles here. The customer service is top tier. Not only that, but any time I have need service/maintenance done on my vehicle - I've had amazing experiences. The service manager will do his best to work around your schedule and help you get from A to B in the meantime. Completely stress-free every time. Highly recommend Certified Auto brokers!
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 recently had my 2025 Cadillac XT5 serviced at Prestige
I recently had my 2025 Cadillac XT5 serviced at Prestige Cadillac and received exceptional service from Aaron. He was professional, patient, and extremely helpful throughout the process. When my vehicle needed to remain at the dealership for 72 hours, Aaron contacted multiple rental companies and ultimately arranged a dealership vehicle—something I’ve never experienced before. He truly went above and beyond and made me feel valued. Excellent customer service!

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!

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.

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.

Professional staff.
Professional staff. Bennett and Brad Tustin are one of the reasons I purchased my corvette from this dealership. They were never pushing and were able to give me additional information about the car, which helped me to decide to buy from them. I felt as if I was buying this car from friend's.
