Used 2018 Cadillac CT6 for sale near Eastpointe, MI

I would like to thank Douglas Chitren for all his help he made the process effortless in buying my vehicle ☺️☺️ Thanks so much Doug E Fresh!!!

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.

I purchased my 2026 Equinox RS AWD on 7/24/25 and on 7/31/25 it had a ?reduce acceleration, drive with care? warning on the dashboard. On 8/1/25 made an appointment with John B. and he was able to expedite the service, since it was a brand new vehicle. Turned out to be the oxygen sensor, which was replaced under warranty. I still felt like it wasn?t accelerating well, so I took it back in on 8/13/25 and John B. helped me again. Nothing was able to be duplicated and no bulletins are out, so I?ll just have to wait it out. Luckily I am still under warranty, but it?s just unfortunate when this is a brand new vehicle. I also spoke to Mike, the general manager and he has been very helpful with figuring this all out. He also had me bring it back in on 9/3/25 for service with Tony. I was told there?s a bulletin for low acceleration, but GM hasn?t put out any codes or repairs yet. They also put in a TAC report. So we?ll see what happens next.

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.

Mike R. has been taking care of my family and servicing our vehicles over 40 years! Nothing but the best. Al and John are some of the best service desk representatives and get my paperwork done every time.

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.”

Lonnie was one of the best salesman I’ve ever dealt with and the overall experience at the dealership was amazing

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.

Andy is an amazing salesperson. He loves what he does and it truly shows! He’s amazing and kills it, he got me the car I wanted and I love it!! He was so patient, very helpful, and kind throughout the whole process. We need more like Andy! Thank you for all that you did Andy!

Finding value in a used automobile is difficult, but Moe at Car Dome Auto Sales ensured I got the most bang for my buck. After discussing my budget and requirements, Moe showed me cars with the best characteristics for the money. I didn't feel like I had to sacrifice quality to keep inside my budget. The entire process felt honest and fair, and I drove away feeling I had received a wonderful price.
