Recall Service Review
My recall service appointment on 9/7/23 was reschedule by Jason Jackson. The reason was the tech going to be out for my original appointment which was 9/8/23. Jason Jackson service consultant at Suburban took care of me very well, I also ask him can we do the works package for an oil change with tire rotation. He said sure we can fit that in with your recall. Jason customer service is always on point and over the top.

Highly recommend!
Highly recommend! Carter helped us and was amazing. The whole process of trading in my vehicle and getting a new one was smooth and easy. They helped me get a good trade offer over the phone from 4.5 hours away and had the best deal I could find on a used Highlander. You won’t be disappointed!

Great team
Due to the current truck shortages dealers have been adding $5-15,000 over MSRP but you guys stood by your MSRP price. They also met me in NY at airport with my truck to save 5 hours off of my return drive. Couldn’t have asked for a more simple process and great team to work with. Thank you for all the help.
best in class
My GMC Sierra is the best ride I have had in all the years that I have been driving. I started driving in 1977. I love my new Sierra.

Super impressed and happy with my 2024 BMW M3 Competition I purchased at Baha’s. The car’s beautiful, rate was awesome, and the whole experience was wonderful
This is an attractive and enjoyable vehicle.
I traded my Chevrolet Silverado for this GM Certified GMC Sierra 1500. It is an attractive and enjoyable vehicle. Some years ago I had a GMC and really prefer them over a Chevrolet. This vehicle is just what I need for hauling and general driving.

After having a difficult experience at another dealership
After having a difficult experience at another dealership I called Lupient GMC in Golden Valley and they found me the exact car I wanted in a matter of hours. From start to finish, the process was seamless and stress-free and the customer service was outstanding. Jeloni was incredibly professional, knowledgeable, and attentive, ensuring that all my questions were answered and that I felt confident in my purchase. The entire team was friendly, welcoming, and truly made me feel valued as a customer. Their dedication to providing top-notch service is evident, and I couldn't be happier with my new vehicle. I highly recommend Lupient GMC and Jeloni to anyone in the market for a new car—this dealership sets the bar for excellence.
