I along with my wife have been customers here for almost ten years and have purchased several v professional folks at Hennessy Porsche North Atlanta. I along with my wife have been customers here for almost ten years and have purchased several vehicles from this dealership. We have worked every time with Mr. John Dissen, who in my opinion is the penultimate professional. He is kind, extremely knowledgeable about this company and its vehicles, and goes above and beyond to ensure that his customers are treated with kindness and consideration. He helped me to coordinate an amazing surprise birthday gift for my wife!! It is always a pleasure seeing and talking with John whenever we are at Hennessy Porsche, no matter for what reason. Additionally I must also mention how professional the rest of the team here is well, from the GM to the service professionals. The facilities are also impeccably clean and inviting. A truly exceptional dealership!! More
