The entire team at this location far exceeded our
The entire team at this location far exceeded our expectations! Our sales consultant Sandi was extremely easy to work with, and he had our best interest in mind when working on a deal for a new truck. When it came time to financing, Alex ensured we got in and out with exactly what we needed. He provided us personal stories bridging to his recommendations that help guide my wife and I in a direction that surpassed what we originally had in mind. Finally, throughout the visit Edgar and Manny ensured we felt comfortable as we worked though a deal that would ultimately have us driving home without any doubts in a vehicle that can grow with my family. They were the cherry on top to an already excellent experience. Thank you from the bottom of our hearts for such a great team!
Great Buy!
This truck is amazing. Turning heads all over as we tour the area. Those riding with is also enjoy the comforts and safety features. Great Buy!

I bought a used Buick Encore.
I bought a used Buick Encore. The car is running great and is in great condition. The whole process was smooth. Everyone was friendly and professional. All my questions were answered. The car I wanted to test drive was ready for me when I got there. Simeon Talevski was my sales agent. The General Manager was also very professional, friendly, and made sure I understood everything. I am glad I bought my car there.

I normally don't do reviews, but had such a great experience with Advantage Chevrolet I'm making an exception. I found a vehicle online that I was interested in, reached out to Advantage Chevrolet and was put in touch with sales person Andre Thomas. A phone call and three texts later we had a deal. I flew up, he picked me up at the airport, and we got the deal completed quickly and as discussed. I was a little cautious buying a car out of town, but Andre assured me it would be as described, and it was actually better. Everyone at the dealership was fantastic and were long term employees which I find rare in this industry.
