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.”

The salesman I dealt with, Rob Fulmer is one of the best.
The salesman I dealt with, Rob Fulmer is one of the best. Strait forward, tells you how it is without any hidden surprises. He was honest, patient and very professional. He easily addressed all my concerns and questions and I would highly recommend asking for him to be your salesman. He was very quick in responding as I was inquiring about a car out of state and he made everything very easy and simple to understand. Out of the other dealerships I inquired about, it was like night and day. I ended up replacing my engine in my old vehicle, so I didn’t actually buy from here but everything was set up to go I just had to sign. He was honest about out the door pricing and the dealership he works for doesn’t try sneaking ridiculous hidden fees like some of these other places. This review is the least I could do since I pretty much wasted his time. Thanks Rob and sorry again!
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.
