Great Used Car Purchase Experience
Working with Brandon Ozier was a good experience purchasing a used CT6. It was done quickly - 5 days start/finish. I came from out of town and he accommodated my schedule. The negotiation was fair. The car’s detailing was done poorly by a 3rd-party prior to my arrival - Brandon worked to fix it himself. I appreciate the good sales experience.
Cadillac hit a home run with the CT6
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.

Used 2013 Toyota Camry
This was my first car buying experience. Garrett was helpful and pleasant. He was not pushy at all. I would recommend this dealership and Garrett in particular.
Beautiful and comfortable car
It is easy to navigate , good for gas, quiet but still shows the work of the engine. Warms up quickly and has luxurious look.

I would like to give Taylor Rogers ATM on being a good car salesman appreciate everything that you guys did for me appreciate the payments I appreciate and love my car
Car size is good, considering the market for sedan
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 ?????

The people at this dealership are totally customer oriented and serve them with utmost care.
Great value
Almost all options are included in a specified trim level so purchasing is straightforward. “Infotainment Center” has an overwhelming combination of great GPS navigation, electronics inter-connectivity, communications, and entertainment features. Enhanced safety features are impressive, from notices (visual and tactile) of cross-traffic backing out of driveway, to blind-spot warnings, following-distance display, etc.

Great experience dealing with Jeff and Martin!
Great experience dealing with Jeff and Martin! I will definitely go back and buy from them
Standard of the world
I’ve owned a wide variety of cars, Maserati, Mercedes and BMW. I always go back to Cadillac. The quality is top shelf. Interior design is way better then the Germans, especially BMW which I feel is the most hyped car in the world. The ride in my CT6 is comfortable but not floaty. It gets good pickup fro the 335 hp V6, but I feel a V8 option other then the Blackwing would be nice. I hope Cadillac comes out with a full size replacement for the CT6 by the time I’m ready for a new one.

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.

Once again, prompt professional service.
Once again, prompt professional service. I brought a vehicle in for Va state safety inspection. A problem was found with a suspension component. I was promptly put in a loaner vehicle and repairs were made the same day under warrantee. Very happy with the outcome and the fact that they valued my time enough to put me in a loaner, so I wasn't tied up at the dealership while repairs were made.

I recently had the pleasure of purchasing a Cadillac from
I recently had the pleasure of purchasing a Cadillac from the Naperville dealership, and I can't speak highly enough about the outstanding service provided by Sales Associate Max DeMare and Finance Manager Sherri Pacchiano. From the moment I walked in, Max's friendly demeanor and deep knowledge of the Cadillac lineup made the selection process seamless and enjoyable. He patiently answered all my questions, ensuring I felt confident in my choice. Sherri's expertise in finance was equally impressive. She walked me through all the available options with clarity and professionalism, making what can often be a daunting process feel straightforward and stress-free. Her transparency and attention to detail were truly appreciated. The level of customer service I experienced here is truly commendable. Both Max and Sherri exemplify what it means to go above and beyond for a customer. If you're in the market for a new vehicle, I wholeheartedly recommend reaching out to them. Their dedication and professionalism set a high standard in the automotive industry.

Bumper to bumper but no coverage on accident spilled liquids. The shifter should be sealed better. GM knows that you may accidentally spill a liquid. Shifter too close to cup holders.

I had an exceptional experience purchasing a used Lexus
I had an exceptional experience purchasing a used Lexus LC 500. Cris Sanelli was fantastic to work with, making the process smooth and efficient even though we were 2.5 hours away from the dealership. Most of our communication was done via text, and Cris was excellent at answering my questions and providing detailed videos. He kept me updated throughout the process, making the experience a pleasure. The negotiations were straightforward, with most of the details finalized before I arrived. Ivana Johnson was also wonderful, guiding me through finance options and securing an unexpectedly great rate. She was friendly, informative, and made the entire process easy. I would definitely travel to Grieco again for my next vehicle purchase.

I very recently bought a 2025 LYRIQ from the Sewell
I very recently bought a 2025 LYRIQ from the Sewell family. I have exclusively driven Acura’s (10ea) for the past 15 years but decided to take the plunge and go all electric. Acura didn’t have a good option, so I did my research and settled on the LYRIQ as the best option balancing design, reliability, and the features I wanted. I tried a dealership in the far North Houston area and while they were nice, they lacked follow up when I decided to make a purchase. I then tried Sewell and am so glad I did. I have to say it was the most hassle-free experience to buy a new car in nearly 50 years of experience. My salesperson was Cailee Thames, and she was fabulous. She answered all my questions, and I very quickly got what I think was an exceptionally fair price, based on my research. I never had to go through the traditional drill of “let me get the sales manager” who then wants to upsell. I dealt only with Cailee. Since I needed my wife to come back and make the final decision, I was prepared to pay a deposit to hold it, but Cailee said that’s not the way they do business. A handshake held the car for several days before we could get back. Everyone I came in contact with was very professional and focused on the customer. All the closing documents were done online and provided in print form. Of course, the car was flawless, inside and out. About a week after I got the car, I decided I wanted to get the Tesla charger adapter. I called the closer dealer, and they quoted me $400+ so I went back to Cailee who got it for me at $225, as we had discussed earlier. I live a long way from them and wanted it shipped to save the drive and expected I’d have to pay for shipping, but no, the parts department said they would take care of it, and it went out the same day. So, my bottom line is that the Sewell dealership does treat you like a “customer for life” from the beginning of the experience. I can highly recommend buying from Sewell, even if they are not the closest to you. And if you’re lucky enough to be assigned Cailee, you’ll be even happier .
