When I meet Greg for the first time I knew the kind of customer service I was getting, very professional, well trained, detailed and honest. I deal with customers all day long and I know the importance of a first impression and long-lasting relationship, I felt very impressed with such remarkable customer service from Greg. He explained everything I needed to know about the car I was buying, very helpful, detailed, made me feel very positive and confident, he showed me around, had the patience of walking me thru the whole process, then he brought me with Jeff the finance person, I really had a great experience with Jeff as well. I wish I had more words to explain how happy I am with my purchase, grateful and lucky I meet Greg, I will definitely recommend him and Dupage dealership to my friends and family, thank you Greg!!!
