Used Cadillac sedans for sale near Rosemont, IL

great, helpful, friendly ,knowledgeable staff. explained and answered all questions. followed up with a phone call ,and when I called them they called me right back.

This is a very good car but it must be driven like the big car it is. I have 115000 miles on mine, bought it with 89000 four years ago. I have had some mechanical issues but all cars do at this mileage. The mpg is low (9-11 local, 25 highway) but the ride makes up for it. The car cant be beat for road trips and I still get compliments on the look of it. I budget 100/ month for upkeep plus 15/month for tires. Over the long haul this has been very close to actual costs for repairs and maintenance. It is a great car .

Great experience salesman was awesome. Took only two hours from the time we got there till the time we were driving off the lot bought a really nice car for a low amount of money.

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.

I previously leased a 2014 and was heartbroken when I had to return it end of lease in 2017. I picked up a used 2015 in 2020 and it has been as much pleasure to drive as the previous one. Both were 2.0L turbos, 4WD. I am in Canada, and it performs well, especially in winter, with winter tires of course. The ride is stiff but responsive. Comfort is great in the front. Consider this a two-seater unless you are only putting young kids or people you dislike in the cramped, unheated rear seats. Everything about driving this car is a joy. The acceleration, the handling, the sound system, the brakes, I could go on. Everything about the CUE system is of course abysmal. The design, the reliability, the fact that every once in a while it comes up with a nag screen reminding you to keep your eyes on the road, which you have to take your eyes off the road to dismiss. I bought the 2015 with a broken screen, knowing that I could replace it myself for 1/10th of what the dealer was charging, as I had to do this with my SRX - twice! Both side mirrors have failed and are now secured with epoxy. You would think that a company that has been around for 100 years or so would know how to make side mirrors? But I know that they also don't know how to make headlights, because (as already mentioned) I also own an SRX. If you can put up with the annoyances (which I can), this is a great car.

The staff here is tremendous! Not a single staff member walked by without acknowledging my wife or I. These guys know how to make someone feel welcomed here, the stigma of having a car salesman be pushy doesn’t exist here! Our sales man David Escobar helped us find the perfect suv and worked the perfect deal. Can not say enough good things about him, worked through everything, explained everything thoroughly and then some! Bottom line if you’re looking for a new vehicle and don’t want to deal with the drama this is your place to be without question.

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

always excellent cuatomer service and good attitude and wait time always accurate and personal staff is great!

I wanted this car... Value for money is excellent for this level. The twin turbo V6 is plenty powerful... The quality and attention to detail is apparent. Rides great! Handles great! Can choose between touring and sport mode mode ..sport mode tightens everything up and makes the exhaust note more aggressive..And it's American.

We walked in looking for a new or lightly used Cadillac. Coach Novak approached us and was absolutely fantastic. He was right he isnt a typical salesperson. He wasnt the typical slick talking, fastmoving stereotypical sales guy. He was respectful of my wife and my time and our needs. We got an great deal on a beautiful Cadillac. Thanks Rizza and Coach for all your service and attention in our new purchase.

I have had this car for 3 years so far. I love it! The car itself is very lively and can speed up very quickly. It is a comfortable car to sit in and while it is small that is why I bought it. The leather seats are comfy, and the seat warmers work well. It is great on gas mileage, and I find it does not take above 50$ to fill up. I commute to work daily, and this car is reliable and fun. I have had issues with this car such as the transmission wire harness needing to be replaced and the rear axle dif leaking and needing to be replaced. I also had an engine crank shaft house crack and that caused my car to stall. Other than these few minor issues it has been great. The car has a decent entertainment system but sometimes the CUE system lags a little bit. The electronic readings on my fuel MPG and my fuel tank estimate are wrong usually but they are about correct to the true reading. I would buy this car again.

Great staff and very good deals on new vehicles. Quick, friendly and very helpful. I would recommend if your looking for a great deal check with these guys first. They will get you that Great deal others can't.

Although we could not agree on a price, Kourtney was very helpful; very knowledgeable about the product. I enjoyed working with her.

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.

Great service! I felt welcomed and at ease. The staff were very friendly and I didn’t feel pressured to buy!

This suv is exactly what I was looking for. It has a great exterior and interior appearance. The ride is smooth and very comfortable. The features of this vehicle are just what I wanted.

Good dealership with much inventory. And the salesman was very helpful. He helped me finding exactly the car that I wanted. The salesman is named Ivalin Nikolov.

Great dealer and salesperson at Classic Cadillac. Was best car buying experience in 20 years! Every thi n g you would expect from a Cadillac

On August 9th, 2025, a family member requested my assistance in purchasing a car at McGrath Acura dealership in Westmont, Illinois. Our salesperson George provided exceptional support and enthusiasm throughout the process. Although the exact color we desired was not available, George diligently demonstrated alternative options while his manager searched for the desired vehicle. Their joint efforts culminated in a remarkable outcome. After careful consideration and negotiation, we ultimately selected the available alternative. The conversation with George, the manager, and George, our sales representative, was highly enjoyable. Both individuals demonstrated expertise and provided comprehensive answers to our inquiries. They genuinely prioritized our satisfaction. I highly recommend McGrath Acura to anyone seeking an Acura vehicle. Make sure to talk to George in sales!

we love the car! being a Cadillac, I figured the fit and finish would be of better quality. driver door was out of line took back to dealer and they made it better, but not perfect. Little disappointed

I've known the service manger, Marc Kubil, for almost 20 years. I can't think of anyone more capable and trustworthy. He goes above and beyond to make sure you are competently satisfied. Robert Fellows is also outstanding, as is Jamir Garcia. At Volvo Oak Park, I'm treated like family, and have received consistently great service.

It’s a new car only had 5 miles on it when purchased check with me in a year to see if all accessory’s work and how Turbo functions

I was very fortunate to have the greatest salesman, manger, General manager and finance director in the business assist in my purchase. Thank you "Coach" for all you do for me and the family

Wide selection and no haggle are a plus over other dealerships. I like being able to see how many different makes and models. CarMax is the only place I will shop

I purchased this car about three weeks ago. I love it. It is so fun to drive and so comfortable inside. I will buy another one at some point.

Sherry was amazing & did an excellent job at finding us the suv we wanted. We would definitely buy from her again and she became a great friend! The entire experience was seamless. We couldn’t be happier.

In my 20s, I had a 2005 Cadillac CTS in red. It was a wonderful car—super fast, and I loved driving it. It was both sleek and powerful, and honestly, that car was my world. I regret not keeping it, even though it needed thousands in repairs. Fast forward to today, and I have another Cadillac. She’s beautiful, but she’ll never be my first love.

Great customer service.Thank you Fil, Greg and Ulises for making every step as easy and hassle free as possible,Quality vehicles at reasonable prices.

Rides a little stiffer than the Deville. Has a smaller gas tank and lower MPG, but this is the big model available after the Deville was discontinued. If you like the comfort ride, this is your car. I have the Platinum model, and it is decked out. Still trying to find some of the features!

If you are looking into getting a new vehicle, DO NOT go anywhere else! This was my first time buying a car and I lacked knowledge in what to look for or what to expect during the process. Frank Amadeo was incredibly patient and guided me every step of the way. I appreciated his honesty as well as his answering my every question. He strived to get me the best deal possible which he accomplished and than some. I was helped also by Kieth who was incredibly personable and aided me in the process, as well as Luis who guided me through my new vehicle technology as well as talked through my questions I had about my vehicle. Overall I could not have asked for a better experience, I will be telling everyone I know that this is the place to come for all their vehicle needs. Thank you!

I recommend the 550T option. What a fun driver. The interior height is low if you have the sun roof option. The new colors are great as well.

I had a fantastic experience at this dealership! From the moment I contacted the dealership while I was in Tennessee, I flew in, and the staff was incredibly friendly, welcoming, and professional. Uri (The rep) took the time to answer all my questions, made sure I felt comfortable, and went above and beyond to help me find the right car. The entire process was smooth, transparent, and stress-free. It’s refreshing to deal with a team that truly values customer satisfaction. Highly recommend this dealership to anyone looking for great service and an amazing team!

Got a 2013 about a month ago with 60K in nearly perfect condition. I have spent some time and money fixing little things - these cars are complicated and loaded with delicate technology. The CUE radio has been replaced, as has the electronic dash - which are both a very nice feature but are known to fail. It drives beautifully, has tons of room, is a fantastic value proposition, and looks very nice. The overall finish is very high and of very good quality on these cars. The owners complaining here are the ones that drive them hard and the only attention the car gets is when they drop it off to the dealer for something and then agree to fix things. Plan to spend a lot of money keeping one going if this is you. If you can do most things yourself, and keep it properly looked after, it's typical of any common luxury car. They ALL have their quirks. If you really wanted a toyota or a honda economy car then this isn't the car for you - go buy one of those, you'll hate owning one of these. Me? I just love it! Next costly maintenance is the magneride suspension - it does wear out, and typical engine cleaning - valves, injectors, plugs, etc. All fluids are new, brakes are new, tires are new. Everything is expensive for these cars.

This place is amazing! The selection of high end rare collectible cars is simply eye candy for the soul. The vehicles are fairly priced and there’s no haggling required. The owner, Michael Colby, and his staff are all pleasant and easy to work with. They love and appreciate these cars as much as the customer and it shows! My car purchase was easy and enjoyable. You must check this place out, if you’re looking for a premium pre-driven vehicle. Im going to be telling my friends about this place!

I’ve owned Cadillacs since 1979. This is by far the best fit for size and comfort. Not a “boat” but big enough for a family trip.

Sheri was excellent and accommodating to deal with since we had an insurance claim to deal with to purchase our next vehicle. I would highly recommend the dealership and asking for her.

Best car I ever owned. Extremely reliable, very comfortable. Every time I think about upgrading, I look at it and say why….lol it’s that good. Highly recommend this automobile.
