Excellent team to work with across the board.
Excellent team to work with across the board. The entire process was painless albeit time consuming. Would definitely recommend for anyone looking for an easy to work with team.
Overall I am very happy with my new Truck.
Overall I am very happy with my new Truck. GMC however needs to address their software glitch where the display screen intermittently stops working or the audio cuts in and out. I keep hearing a software update is being worked on but that was a while ago?

I have the 1500 double cab with standard bed.
I have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.

I drove over 1,000 miles to come to this dealership and I’m glad I did. They took care of us quickly and were very communicative throughout the whole process. They sent me pictures and videos so that I could know what I was getting even with being far away. Great group of people and very friendly and hospitable. Would definitely recommend this dealership. Thanks Staton for the easy car buy.

I can’t say enough about how positive my experience was with this store. They worked so hard to work with us and get us the best deal possible. I never felt like we were on opposite sides. I went in a bit nervous but never felt like they were pushy or trying to wheel and deal me. I felt very taken care of and like they were on my side. I highly recommend!

Every person involved in the engine replacement of our
Every person involved in the engine replacement of our family truck should get some sort of bonus and/or recognition for saving our family vacation. They somehow pulled enough strings to get my new engine ordered, shipped, installed, and my truck back to me in about 2 weeks. That allowed us to have a vehicle large enough to tow a boat and have 4 adults comfortably riding down the road.

My recent purchase of a Chevy Traverse from Mills
My recent purchase of a Chevy Traverse from Mills Chevrolet of Davenport was a tale of two halves. Initially, the salesperson seemed to make getting the rates I wanted impossible, stifling any negotiation. But then, the sales manager stepped in and completely turned things around. He made sure we got the car we wanted at a great rate, making the rest of the process seamless. The manager's intervention truly made all the difference and earned my satisfaction.
