    I have a ct6 platinum with super cruise.

    I have a ct6 platinum with super cruise. 4 years now bought used . I have driven it 60k miles. Not a single problem. Normally gets 30mpg with the 3.6v6 on highway about 24 in town. The car handles fantastic on any surface. I love it. Highly recommend it.

    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.

    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.”

    Car is a pleasure to drive.

    My vehicle is an excellent car to drive. The CT6 is a great handling, smooth, comfortable driving vehicle. This is my third Cadillac that I am driving and plan on continuing to drive one.

    Most enjoyable car I have owned

    This is my second CT6. My first was a lease and I decided on an XT4 as my next car. But ran across a Crystal Tricoat beauty with Cinnamon Interior and Supercruise and just had to have it! I loved getting back into the comfort, performance, value, and style that this car has. I feel it has a great understated presence.

    This car met all my needs. The ride is excellent with plenty of space. My grandchildren love the entertainment center. They are able to watch Netflix, YouTube and others in the backseat. I love the 2018 Cadillac CT6.

    Car glides over bumps, and you cant even notice ha

    The car met most of my needs. I was slightly disappointed with the comfort of the front seats. It seems that on a long trip the cushion gets flat and hard. I have owned over 10 cadillacs . I have had eldorado, coup de ville sedan de ville seville DTS and a CT6 which feels like an extension of the seville. And all of them had plush seats. I get that cadillac wants to open to a bigger audience by presenting a tighter more performance seat but, they are loosing their base like me. Please get back to the large flag ship model.

    Luxury! This car is great on the highway or just moving around town. Lots of power for a V6. Lots of leg room front and back seats.

    Looks, Power, Comfort and just plain FUN

    I've owned many luxury cars, but this CT6 is without a doubt the most comfortable, most luxurious and least complicated hi-tech automobile I have experienced. We have had Lincolns, Mercedes, Volvos and Cadillacs previously, but none of them compare to this CT6 with 404 horsepower. Most impressive is the gas mileage, though we didn't think about it when we bought the car. Surprisingly, this 2 ton car is getting 27+ miles to a gallon of gas. We just had a fabulous trip with all our luggage and gear. What a pleasure to drive, and SuperCruise makes for a very relaxing ride. If you want luxury, hi-tech, comfort and lots of fun driving, you WANT this car.

    Terrible car - while it looks cool, not practical

    Car looked cool - and it stopped there. While fine on a 30 minute test drive; bought it and drove it 2 hours. Seat is uncomfortable. Cockpit layout is not good. Location of heat/ac vents are poorly placed. I could go on. Medina, Ohio Cadillac dealer was a terrible experience. Dumped the car and took a huge loss. Will never buy a Cadillac again.
