The young lady was extremely attentive and helpful. I haven't purchased yet but I'd purchase with Crest.
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.

Overall good drove over three hours to arrive, pain that policy is they don?t accept checks or certified checks when purchasing outright. Did money transfer before leaving home and waited an hour at dealership for verification of transfer total four hours (ridicules). Other than that process was simple enough.
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.

Honesty
I was attempting to purchase a clean looking Chevy Colorado and worked with Kyle Brewer. I am out of state so Kyle worked hard to show videos, answer questions and do an iphone facetime walkaround of the vehicle with me. I never did get a chance to make an offer. The following day when I called the dealership Kyle was away but I spoke with Julian Henson and he informed me that they could not sell the vehicle due to an improper and unsafe lift kit installation that made the vehicle unsafe to drive. Their honesty saved me time off work and flight costs. Had that been a dealership in MY area I would have had an unsafe vehicle pushed on me. I never once felt pressure to purchase and felt treated fairly and honestly throughout the process. I even received a call from the manager afterwards to follow up with me. Would be more than happy to do business with them in the future.
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.

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.”

It was definitely worth the stop!
I stopped in with my son, a first time buyer who was looking for something to tackle the snow with. As soon as we stepped out of our vehicle, Dominic approached us with a friendly aura and introduced himself with a smile. Ya know, most of the time when you’re greeted that fast as a auto shopper you’re thinkin’ uh-oh another pushy salesman, but that was far from the case. This dealership was helpful and willing to give us a car buying experience that was unmatched by previous lots around the region. The staff is friendly and treat you as one of their own. I will send all of my friends and family here first the next time they’re lookin’ to buy a car.
Bought a few months ago like this one didnt give p
runs good never gave me any problems and still have it until this day wasnt a bad purchase i recommend this car for anybody who likes them

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!
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 ?????

GOOD RAPOR WITH ALL CONTACTS THUS FAR, ALSO GOOD INFORMATION PROVIDED. PLAN TO STOP AT THIS LOCATION TO VIEW THE BLACKWING/S.
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.

It was a good experience. The salesman said my offer was too low. I said that I would pay cash. I hoped he would make a counter offer but he didn't. Perhaps he already had a higher offer. Larry Henderson
Great Luxury Vehicle
I’m really enjoying the smooth ride and luxury features. The panoramic sunroof view is amazing and the comfort of the sedans leather interior is unparalleled.

Love this car.
I love everything about the CT6. I have a 2019 Sport twin turbo model and it’s a dream to drive. Fast and responsive when I want that. Smooth and comfortable when I want that, too. I bought it because of the self driving system Super Cruise, which is the best self driving technology available — better and safer than Tesla. I also love the exterior styling and the interior design. The Cue system is great. The legroom in the back is the best I’ve ever had. Seriously, this is an amazing car. It baffles me why Cadillac stopped making it. They didn’t market it well. If more people knew about Super Cruise, that alone would have sold a lot more cars. GM screwed up big time when they canceled this car. They should have tried to actually sell more by investing in marketing it. NO ONE knows about Super Cruise. Add on the performance and styling and it’s the best car I’ve ever owned.

Very professional! Sales team are very friendly. Unfortunately, the vehicle sold the day before I was scheduled a visit to look at it.
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.

This Cadillac CT6 is by far the best value for my money. It is solidly built, quiet, and smooth. The ride is like a Mercedes-Benz and it handles almost like a sedan. It's just the right size, has very comfortable seats and is loaded with technology!
