First off, the mechanic did a good job on the car.
First off, the mechanic did a good job on the car. No complaints. The customer service was alright. I stood in the tiny service area for a few minutes waiting for someone to help and no one said anything to me even though there were 2 employees there. No complimentary snacks. Only a small complimentary coffee. They have snacks but you have to pay the vending machine. I shouldn't complain, but Mazda has a variety of complimentary snacks AND refreshments in their waiting area. Overall I would go back, but I wouldn't look forward to it.
this car is truly amazing
Got my CT5 about 5 months ago...it is everything I expect from Cadillac. Love the interior and the exterior style reeks of class and performance! The police have flagged me down only to compliment the car! I'm a GM girl and they continue to make me proud. LOVE my CT5! :+)

Best Cadillac Ever
The CT5 3.0 premium car is fantastic. Price was not an issue when I was shopping. Compared to Mercedes, BWM the CT was best. Great power and comfort with all the latest technology

I’ve been a Germain BMW customer for years and find the service department to be excellent. My service representative, Tona Zorelli has consistantly provided excellent service. She’s always friendly and communicative.
CT5 Is a Winner
My first Cadillac (66 years old) and Wow what a car. The 2 liter turbo just flies and the styling is head snapping. Looked at the foreign luxury counterparts and my decision was easy.

Was an excellent experience and fast handling of car schedule Maintenance by the all crew.
Cadillac has uped the ANTE.
First, this is not a small car. Not huge, but noteworthy. Second, this is a 2.0, 4 cylinder that absolutely shines! I'd read reviews claimed it's unimpressive and sluggish. No, this ISN'T a race car, but it was certainly whisk through traffic and engulf the highway with nimble agility. Modern electronics and wireless CarPlay make this a wonderful driving experience! Gorgeous lines, ample lighting and a decent sized trunk make this your next favorite sedan.

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

This my 18th cadillac and by far the best one yet. It has all of the modern conveniences. Very classy, stylish and responsive. When stopped for gas or at a stop light I get complimented on the beauty of the car

I had an outstanding experience purchasing my Toyota with Jayson Flores! From the moment I walked into the dealership, Jayson made me feel comfortable and confident about my decision. What stood out the most was his honesty and transparency throughout the entire process. He took the time to explain every detail, answered all my questions thoroughly, and never once made me feel pressured. It’s refreshing to work with someone who truly values integrity and customer satisfaction. If you’re looking to buy a Toyota and want a smooth, trustworthy experience, I highly recommend asking for Jayson Flores — he’s the real deal!

Stopped by the Autonation Cadillac dealership to get more
Stopped by the Autonation Cadillac dealership to get more information and take a look at the new 2026 Lyriq. It has changed a bit this year. I met John Hoover. He is the most knowledgable Car Sales Person I have met in decades. He actually showed me things about the car that I didn't see/know from my online research. We left the dealership to think about the cars we had seen that day. Four days later, I returned to purchase. The process was very smooth. I met Mayara in the finance department and she had me on my way quickly. I will defiinitely return to Autonation and John for my next one.

I recently purchased a vehicle from John Hiester CDJR of Sanford, and I couldn't be happier with the entire experience. From the moment I walked in, I was greeted with genuine warmth and professionalism. The staff was incredibly knowledgeable, transparent, and never pushy—something that's hard to come by these days. My sales rep, Tajh, went above and beyond to find the perfect car for my needs and budget. They answered all my questions with patience and made the process smooth from start to finish. The financing team also made everything straightforward and stress-free. Highly recommend Tajh and team at John Hiester CDJR of Sanford to anyone in the market for a vehicle. This is how car buying should be!
