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.

Melissa helped me find a car at the last minute. My previous car was in bad shape and I had to find a reliable car quick and fast to get to work .She went out her way with a smile; ensuring I was confident with this purchase . She is honest and demonstrates integrity. I will recommend her. She found me the right car with no pressure, just a willingness to see me find a suitable car. Great job Melissa!
Amazing...and American!
Recently bought a used CT6 w/2.0 Turbo (2018 with 39K miles). Have put only about 500 miles on it so far, but, WOW!!! This car is amazing! This car lives up to it's reputation as a builder of premium American luxury vehicles. My las t Cadillac was a 2000 STS...which was mediocre by comparison. It is soooo beautiful inside. I like that the screen is integrated into the dashboard. It's size takes a bit of getting used to, as my last car was a Mercedes E250. I test drove the 2.0 turbo and the 3.0, and found the 2.0 Turbo to be equally responsive but smoother. Exterior styling is simple clean and exudes luxury. I get so many compliments, heads turns and such. I love the Apple Car Play feature that projects what's on my phone to the in-dash screen. Recently did a road trip and got an AVERAGE of 33.4 MPG on the highway. I am getting 25 MPG+ around town. To me, that's pretty impressive for a car his size. In keeping with Cadillac's reputation, this car drives so smooth and quiet. Last time I drove a car this quiet and smooth as a Lexus LS460. At $30K less than the price of an average EV, it will take a lot of gas to make up the cost difference of those overpriced cars.

The Perfect Luxury car
I purchased the CT6 Luxury AWD new in 2017. I haven't had any issues at all. I love the double sunroof and the 360 camera view. But what I am really upset about is GM discontinued this model. It is an awesome driving car and I won't be getting rid of it anytime soon.

A Praise-Worthy American Luxuray Automobile
Having had my 2018 Cadillac CT6, equipped in the optional Premium-Luxury trim level, for nearly 3 years, I can honestly boast of its many attributes. It offers wonderful styling inside & out, the availability of virtually every current "high-tech" option conceivable, and has proven to be consistently reliable – and, while some may describe it as a bit “pricey,” it’s actually a relative bargain, when compared to its European competitors. The CT6 harkens back to the classic Cadillac sedans of years gone by, as its size, comfort, and luxury amenities remind owners and admirer’s alike, of many of those all-American classics. Although it's a pleasure to drive, even when equipped with the new and improved, 3.6L V6, the optional 3.0L Twin Turbo engine is recommended for those drivers who like a “little something extra” when depressing the accelerator pedal. With regard to performance, it is somewhat regrettable that an (optional) V8 is unavailable in the company’s “Flagship model.” This absence, I suspect, is a rather obvious "nod” to the so-called green energy movement that seems to have “infected” the entire auto industry, of late. In summary, if you’re looking for a full-sized American luxury car – look no further. The Cadillac CT6 “fits that bill, to a tee.”

⭐️⭐️⭐️⭐️⭐️ Exceptional Experience at Cavender Cadillac
⭐️⭐️⭐️⭐️⭐️ Exceptional Experience at Cavender Cadillac San Antonio I had an outstanding experience buying my Cadillac LYRIQ from Cavender Cadillac San Antonio, and it truly set the bar for how car buying should be. I initially shopped at Sewell Cadillac, but they were extremely greedy and unwilling to work with me. That’s when I called Martin Vara at Cavender. From the very first conversation, Martin told me Cavender would give me a deal I couldn’t refuse without seeing any other offers—and he absolutely overdelivered. At this point I knew this was my dealership. I didn’t need to go back and forth and shop around because Cavender put their best foot forward from the very beginning. Martin coordinated everything seamlessly. I spoke with the Sales Manager over the phone, we agreed on numbers quickly, and they immediately removed the vehicle from inventory. While I completed my credit application and paperwork online, they had the LYRIQ prepped and ready to go. Martin called to let me know everything was approved and ready for pickup. When I arrived at the dealership, the Cadillac facility was beautiful, and everyone was welcoming and professional. Within five minutes, I met the Sales Manager—super friendly, knowledgeable, and genuinely great to work with. Any last-minute questions were answered clearly and honestly. While I was signing paperwork, Martin took the time to walk my wife through the LYRIQ, explaining all the features and giving her a full introduction to the vehicle. There were zero surprises—the numbers were exactly what we agreed on. From start to finish, I was in and out in about 40 minutes. That’s unheard of these days. This was hands down the best car-buying experience I’ve ever had—from sales, to management, to delivery. If you’re looking for a Cadillac (especially a LYRIQ), do yourself a favor and go straight to Cavender Cadillac San Antonio and ask for Martin Vara.

Can never say enough about how glad I am that I chose to
Can never say enough about how glad I am that I chose to return to Thompson's for my second GMC purchase. The first time Bobby D. was so helpful that I requested him 2 years later when I returned. He does not pressure you. He finds out what you are interested in and why, how will you use it? He then gives you options that are available. He was able to answer all kinds of questions about how the vehicle operated etc. He is so likeable. I wish everyone who deals with the public was as polite, understanding, knowledgeable and on and on as he is. THANK YOU BOBBY! Oh Yeah, I like my 2 vehicles too!!

Very informative when requesting information via email as requested. Honest and straightforward answers to my questions.
Amazingly smooth, well-made
I'm trading my 2019 CT6 after two years. Have really enjoyed this car. There is no better highway cruising car ever, it's incredibly smooth but tightly built, not sloppy ever. Great gas mileage, very peppy, and beautiful. The electronics are very easy to understand. The only complaint- driver's seat too short, I'm 5'11", long legs, and I had a buy a bolster cushion. Otherwise, I've loved it. Trading up to a BMW 8 series for more excitement.

We drove 5 hrs to purchase our vehicle and it was well worth the drive. We bought a used car and we were treated like we won the lottery and we’re buying a dozen new ones!! Brad Arrington was the best! Everyone we dealt with was top notch. Who knows, someday we may drive 5 hrs just to come back. The Browns Gainesville Texas
MOVE OVER M.BENZ
I purchased the car new and have had it for 6 years, it has been nothing but awesome in many ways. The styling has endless elegance and will always be a good looking car. Being at "this time" possibly the last of the BIG BODY Cadillacs it will remain special in many ways. It is a great driving car with the combination of AWD ultimately makes it a year round car for my location.

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 ?????

Today, I purchased a Nissan Ariya at Auto Boutique. My salesperson was Lou Walker. Lou was great. He was knowledgeable, patient, professional and courteous. Unlike most used car salesmen, Lou was not pushy. He gave me the information that I needed to evaluate the cars of interest to me and the time to process the information. This was my first purchase at Auto Boutique and Lou made it very pleasant and stress-free. If you need a car, Lou is your guy!
Love my Red Shiny Cadillac
This car drives like a dream and the 3.6L Engine gives me that burst of power you really want when entering a fry. Love the Apple Play features that put all the apps from your phone on the screen, allowing me to listen to my audio books. The turn by turn navigation system is really nice and the screen location is just in the right place.
