My mom has bought several cars from this dealership and suggested I work with Victor based on all of her past transactions… I can now see why she keeps going back! Everything was perfect… I felt I got a very fair deal… Communication was smooth and easy. Victor was very knowledgeable when reviewing the new 2025 Buick Envista I purchased. The finance department was also great to work with and thoroughly explained everything. Victor even put a giant bow on the car for me! Thank you again for everything. I love my new car! More
