New and used 2026 Cadillac CT5 Premium Luxury for sale near Sienna Plantation, TX

Jon was very attentive and knowledgeable about the vehicle I was interested in. Jon also followed up with me to ensure I found what I was looking for.

I want to give this review because my salesperson Alvester was the best. He has a lot of knowledge, was always willing to go beyond expectations and always keeps me informed of required maintenance.

Great experience in Service. Friendly and first class treatment. All of the employees are happy and helpful. Highly recommended for Service, New Cadillacs and Pre-owned luxury vehicles.

I had a great experience on my recent purchase at Sewell everyone was helpful and my sales rep was on top on everything, overall I’m very satisfied.

Always love taking my Car to Big Star Cadillac for the best customer service and they always do a great job. They have a deal where you can get 3 oil changes 3 tire rotations 3 car washes for a Cadillac for under $175 not a bad deal I have a appointment next week for my brakes Ty Big Star Cadillac.

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 .

Outstanding service, my vehicle was listed in Cars.com & all of the details were perfectly listed. Very nice salesperson & the transaction was quick & efficient. Highly recommend.

Our experience with Mackenzie and Sewell could not have been better. She replied promptly, answered all our questions and concerns quickly and professionally. We were purchasing from Virginia and ordering a car from Texas was a daunting prospect but the employees we dealt with at Sewell were absolutely amazing. There were no hidden fees, they were transparent about small cosmetic flaws we would never have see in pictures but since we couldn’t be there in person she sent us videos walking around the car showing every detail. Small flaws were repaired for us before the car shipped. Literally, the car is better than we could have hoped for! We are so thankful for the way Sewell treated us and would highly recommend Mackenzie and her team. 5 star experience!

My experience with purchasing my Cadillac vehicle went very smoothly, of course with the help of an excellent saleswoman by the name of Blanca! If you are looking for salesperson that will go beyond the extreme to make sure satisfaction is met, Blanca is that provider! Thanks Blanca!!!!
