Used Cadillac CT4 for sale near Mount Prospect, IL under $1,000,000

The service this dealership stands behind is the best of the best. We were treated like family and received top notch service that went above and beyond our expectations. Buying a car is one thing, but having a dealership treat you so well AFTER the sale for the life of the car is what matters most. I trust Jason and Gainesville Buick, and you should too if you want things done right the FIRST time.

Coulter dealerships have been very good to me with the vehicles I have bought from them in the past. Coulter Cadillac was the best experience yet. I got a great deal and I know it! The deal was mostly done on line and did not change the day the xt6 was picked up. This is not the usual dealership experience. No wonder Coulter has been around for 100 years. Thank you very much, Steve and Nancy

They were excellent!! Quick and easy and very knowledgeable. Traveled two hours and it was worth the drive

Edgar got me the best deal and made the process easy . Thanks for everything hint

I contacted the store to make sure the vehicle was still available, and they responded very quickly! It was, and I made the drive there and ended up purchasing! Everyone was very friendly and helpful!

I leased a 2024 nautilus from Dana Ford . My sales man was Ahmed Khodir. He was very courteous and professional and he really worked with my wife and I and I am very pleased with him. He spent time to go over everything in the car so my wife and I were familiar with all the new gadgets. If anybody is looking for a car, I highly recommend him. Al Rago

Great to deal with, responsive, competitive , good communication and customer. While I postponed my decision on purchasing I would circle back when I decide to buy.

I have the Sport AWD trim in Velocity Red. I’m coming off a 2015 Subaru Legacy Limited, which I loved. There is no comparison between the two cars. Even in sport mode the CT4 has a more comfortable ride. The Legacy’s cabin was a little roomier but the fit and finish on the Cadillac is top notch. Handling is much better too.

Best customer service ever. He is the best, my experience was 5 starts. I will coming back again 👍

Have you ever taken a sentimental journey back to a favorite place only to find that yesteryears landscape may have changed yet the allure and intrinsic beauty of it still shined through filling you with a yearning to make that little spot of the World all yours? Well, that was my reaction when I first saw the CT4. This small Cadillac is very modern looking, yet it inherited the subtle, classic beauty of its distant relatives. The linear lines of its design, (that instantly identifies it as a Cadillac) with a touch of sculpturing make the CT4 appear longer and larger than it is. The handsome modern yet distinctive grill and front end also clearly announces it as unmistakably a Cadillac. Cadillac's designers put some thought in designing the rear of the CT4 giving it an unclutter attractive balanced look unlike many of its competitors' back-ends which shout out "after-thought". (I state my opinion knowing beauty is in the eyes of the beholder). A view of the back of the CT4 boast vertical taillights, another attractive and dateless classic Cadillac signature feature yet modern in their appealing integration around the sides of the rear quarter panels. The Cadillac CT4 presents itself as a nice balance between a small sport and luxury car. I find the modern definition of interior luxury to my liking and its quality and appearance on par, in my opinion, with its competitors which I've sat inside. The CT4 feels like "home". The DIC is easy to read, and the CUE is intuitive and not difficult at all to navigate. Controls are thoughtfully located within reach whether on the steering wheel or on the touch screen. The seats are comfortable and give all the support I need even for a man my size. For a sport car the front seating area of the cabin is surprisingly roomy with plenty of leg room. I do not feel closed-in or cramped in the cabin. As for the rear seating area, it is small and, in my opinion, it is not a car for those with a family nor for those who need to frequently transport others. The trunk is small and not suitable for those who need to haul a lot around. All around visibility when driving is very good and driving safety is augmented by all the safety features that come standard with the CT4. There is very good vision from the large sideview mirrors as well as the rearview mirror. (Speaking of safety features and other desirable options, the Premium Luxury trimline, which I have, offers much more for your money and is well worth considering when looking to buy this Cadillac.). I find I have no difficulty in entering or exiting this car. Some of the many features that tickle my fancy and put a smile on my face are the auto-high/low beam, the rain sensor function, the exterior lighting option which turns on the lights when approaching the car (great safety and convenient option especially at night), the auto locking of the doors (eliminates that nagging question I have when I'm in a rush--"Did I lock the car?"), cornering lamps (so glad Cadillac brought them back). The Bose radio is fantastic. I absolutely love the long linear hood that gives me a sense as to where the front end of the car ends! The CT4 comes with many more options too numerous to list here. The Turbo 4-cylinder engine is powerful and responsive. It took me a couple of days to get use to the fast response and power from it. Driving the CT4 on winding roads is a pleasure and fun. The car moves effortlessly and confidently without swaying. On the straight away it is a pleasure to drive. The ride is comfortable and smooth. I very rarely have the need to drive highways. Most of my driving is local and the car has been consistently averaging around 25 to 26 MPG on premium gas (which is recommended for the CT4). I have not owned this car long enough to attest to the long-term reliability of it but if it is like the other new Cadillacs (and the numerous other GM brand cars) I have owned in the past, it will be trouble-free and very reliable.

Excellent customer service! Was in and out in no time. Will continue to bring my vehicle to Koons

We did almost everything over the phone and it was so easy. Bennie was an awesome salesman He listened to what we wanted and made the experience very enjoyable.

The CT4 is a real driver's kind of car. It has great style and great performance. Having the Premium Luxury model is nice. The leather seating and cold weather package along with many other luxury items makes you feel special.

Process was very simple! Everyone from the sales consultant, sales manager, finance manager were extremely nice and easy to deal with. Was not a long process.

Comparado con otros autos este es precioso mas confortable tiene mucho confort Esto era lo que yo necesitaba Me encanta y estoy super feliz Ahora si tenemos un carro comodo

Julia Vargas was very helpful and kind as well! She also seemed very knowledgeable and we appreciate her service very much!

It was a long wait to receive my car but so worth it. The ride is smooth and very quiet. I love my car and highly recommend it. Seat adjustments are comfortable and work well, even fitting a short person like myself. Reverse camera is a wide and realistic coverage, very helpful. Cruise control is a bit different but easy to learn. I suggest, if possible, a spot to set a purse so as not to entwine with legs. Console is larger for necessary documents and very convenient. At first, I detected a swagger in back but now it is not as prevalent, possibly my adjustment to the vehicle.

Was a smooth pleasant transaction enjoyed how comfortable I was made to feel I would recommend this dealer and salesman to my friends if they were interested to buy a new car

I want to thank Mr. Matthew P. for his professionalism and patience he provided for my husband and I . This young man will go far in life with his knowledge and Patience working with customers. Look out GM, lol. Wishing Matthew the best! We had a great experience at Big Star Cadillac. Thanks Lee & Karla Williams

Nice clean facility, friendly staff and quality service every time. Jose was a great service advisor and explained everything about my service and got me in and out quickly.

I came in, the paperwork was ready, and we bought a car with no surprises! It was a fast and seamless process! Chief was the perfect salesman and found exactly what I wanted!

Dislike the vibration on the driver seat because it does not advise where danger exists just vibrates. Instrument panel difficult to distinguish options. Love the dark blue exterior color

Linda was very helpful. I didn’t have an appointment and was able to get my car ready in a timely manner. Very nice lady. She deserves a raise! Ty

The CT4 is awesome ! Styling inside and out is great. Great Power and handling . Excellent fit and finish throughout. Very Happy with CT4. Several safety features are great to have. An underrated excellent Vehicle.

Customer service 10 out of 10! K was so nice to me and provided great information for me. Will be coming back to her anytime.

I was looking for a luxury small SUV and this car checks all the boxes! Great ride, good power and so comfortable. I can’t wait to drive it every day.

Great place to buy a car very friendly would highly recommend them everyone was very helpful and gave us a good price on a vehicle
