Used Cadillac CT6 for sale near Burr Ridge, IL under $1,000,000

Service was great and they were quick! Great experience as always at Les Stanford. I was able to get an appointment the same week and they were able to address my needs.

They were fair and responsive. Answered all questions. Speed of buying experience was best I’ve ever experienced.

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.

Hector helped us on getting a truck from my wife, he was really helpful, probably the only issue was waiting, but besides that it was a great experience.

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.

The people at Naperville were professional, friendly, and worked to sale me a car. Ben, was fantastic! He followed through, and did his best to make sure I was pleased and willing to secure my purchase. I would highly recommend working with this dealership to pirchase a vehicle. Jamar

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.

Great sales and service. My service advisor Connor is the best. Had a situation under warranty and it was handled professionally by a very knowledgeable tech names Brice. Good people.

It is easy to navigate , good for gas, quiet but still shows the work of the engine. Warms up quickly and has luxurious look.

It was a very smooth experience, Nick Marzullo was extremely helpful - even off of the clock!

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 ?????

Ricardo was extremely helpful and friendly. Unfortunately we couldn’t find the right car for us.

No repairs required runs great beautiful design brakes are squeaking seems to be stalling when going basic speed. Love the interior exterior design comfortable ride

Paul was great and very accommodating salesman thanks for the great sales. Excited to drive my new 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.

Good experience this is our second vehicle in a year and 1/2. Our first was a 2024 Acadia and the most recent was a 2026 Colorado Z71.

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.

The staff was courteous and professional which made for a smooth transaction. Great car at a reasonable price!

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!

Staff is courteous, quick and respectful. Been going here for 10 years. Will come here for next 10 years

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.

I have purchased a new VW Atlas V6 w/ technology at VW Orlando North. It was a great experience and staff keep supporting me in every issue. All staff A+++ specially Brett (sales dpt.) Thank you!

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.”

Best place to shop if your looking for a new auto! Elmer Pierce and Harold Sigle were amazing and so friendly made my car buying experience a great one!!! They were so friendly and worked hard to find me just what I was looking for in a car!! Thanks guys!! I highly recommend you to everyone!!!

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.

One of the best car buying experiences I have had. Rosemarie was fantastic to work with and provided all the information I needed including a personal video of the vehicle. The team at Harper gave me a fair price on my trade in and the sales process was extremely fast and efficient. Highly recommended for your next new or used car, they are a class act.

The car is great a lot of technology in it. The twin turbo has all the power you will need. Not sure about the transmission at this point. It has 8 gear automatic and it seems to have a little problem when coming to a stop- if you don’t come to a complete stop the shifting is a little sloppy. But overall I love it.

It's rare to find a car dealership/salesperson that is straightforward, honest, easy going, efficient, personable, knowledgeable, helpful and a joy to work with. Jared was all of these things. My son and I were super impressed with the employees and the entire smooth transaction. They treated us as a valued customer for sure. I highly recommend and would prefer to deal with the exclusively in the future for all my vehicle needs.

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.

Great place to buy a car. No games or inflated fees. Highly recommend them. Very friendly and helpful and I would go there again without hesitation.

I recently purchased a 3.6 Premium Luxury CT6 with 30k miles, had the transmission shudder after about a month of owning it. Since it has a 100k PT warranty I took it in and the dealer flushed the transmission and replaced it with a different brand, works perfectly now. Took it on a 4000 mile road trip over the holidays. Outstanding ride, 28mpg avg doing 80mph. This car is a joy to drive, plenty of room, plenty of power and excellent ride quality. Would highly recommend. I’ve owned this car for 6months now and have only seen 2 on the road.

Cardinal motors is awesome. The owner is so amazing, the employees are awesome! Go see them! I did not expect to be able to get a car that day but I did and the quality of the cars are amazing! Thank you again guys!

This automobile is a vehicle of dreams Power roomy front and back Movies Massaging seats heated and cooling seats. Dual sunroof s. Shades. I feel special just Driving or Riding

Zach was the guy who helped me out very professional even tho I couldn’t get the car I wanted he tried super good people maybe here soon we can get me into what I want

Just a great car beautiful to look at and very enjoyable to drive short trips and curvy road or long road trips it takes the boredom out of riding or driving and make them something to look forward to
