They found me a 2024 Cadillac XT4 and I love it. My husband and I switch to Napleton Cadillac because they have wonderful followup and my salesperson Jimmy was very helpful and got us in and took great care of us. Isaac made the transaction seamless. Now Napleton has two Cadillac owners for life. It was a wonderful experience at Napleton Cadillac in Oak Lawn.

Cadillac @ It’s Best
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!

I found a 2022 Cadillac Escalade that is a Certified car
I found a 2022 Cadillac Escalade that is a Certified car and in exceptional condition. I live in Skokie and the Pre-Owned Manager Dave and Ed were very accommodating, listened to my needs, and we worked out good deal. Super happy that I traded in two cars for it. Than you Napleton Cadillac Oak Lawn.
Amazingly smooth, well-made
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.

Made Car Buying Easy
I just purchased a used car at Import Exchange in Everyone was so nice, educated and helpful! Michael, the general manager personally greeted me and directed me to cars that fit not only my budget but contained the list of wants and needs I was looking for. I really appreciated the extra time a salesman provided me after I bought the car to illustrate how to connect my phone. Overall, a great experience and I will definitely be recommending Import Exchange to my friends and family!

Good customer service, very polite, nice vehicle.
Good customer service, very polite, nice vehicle. A very clean establishment. I would recommend this company. I hope nothing does not change my mind.
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.

Brian did a fantastic job throughout the entire process.
Brian did a fantastic job throughout the entire process. He was very knowledgeable about all the different features the vehicle and took the time to make sure we knew how to use them. Lisa in the finance department really knows her job and works with you every step of the process to get you in and out as quickly as possible.
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.”

Chris Antzaras at Ultimo Motors has represented my family
Chris Antzaras at Ultimo Motors has represented my family for 2 car purchases at Ultimo Motors East. He made the purchase of my Corvette Z06 so easy. He is professional, knowledgeable and easy to work with. I understood everything. He’s honest too. I will never purchase from another agent. What a great experience!
The Perfect Luxury 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.
