I had an incredible experience at Van Chevy GMC in
I had an incredible experience at Van Chevy GMC in Scottsdale AZ. The team treated me with the utmost respect and care, ensuring I felt valued throughout the process. They went above and beyond by upgrading me to a better car than I originally wanted ? without increasing the price! The professionalism, honesty, and customer-first approach truly made this a standout car-buying experience. I highly recommend them to anyone looking for a great deal and top-notch service! If you're looking for good service, look ask for Cary in GMC office

I'm limited to just 5-Stars!
I'm limited to just 5-Stars! Our family had an exceptional experience at GMC Liberty all due to the service and expertise of Anthony Sanders. We were looking for the coveted 2025 Yukon Denali AT4 (hot ticket item). He knew our needs and was an open, honest, and most importantly a non invasive salesman. This has been our best automotive purchase experience and we couldn't recommend anyone more highly.

We have purchased several vehicles from Tamer at Liberty
We have purchased several vehicles from Tamer at Liberty GMC. He is an amazing salesperson and we continue to go back as he provides us with the best experience. He is a knowledgeable, friendly and no pressure person. I would definitely reach out to him for all your automobile needs. Thenl dealership also has the best finance department we have dealt with by far. Would recommend Tamer and Liberty GMC to anyone in the market for a vehicle.

Outstanding service.
Outstanding service. Worked with Erik for my first oil change in Service. He was super fast, got to the point, gave me accurate time frame for completion and communicated with updates while I was waiting. Also, Robert with customer service was awesome and even offered and bought me a star bucks coffee while I was waiting. Probably best dealership in country.
