This was my first experience with buying a Porsche, and John made the entire process so easy and smooth every step of the way. From the initial test drive, to the build process, to the final delivery and w John made the entire process so easy and smooth every step of the way. From the initial test drive, to the build process, to the final delivery and walkthrough, he was there to help and worked with me to get exactly what I wanted. He also showed a tremendous amount of knowledge about both the brand and the car. By the end of the process, I didn't really think of him as a salesperson, but more as someone who was partnering with me to help make a dream come true. He really made me feel like part of the family. I've bought cars from other luxury dealers before, but this experience was on a completely different level; much more personalized and pleasant. If you are in the market for a Porsche, I cannot recommend John at Hennessy enough. He has made me a customer for life. More
