My expectations for Hennessy were high given my initial contact with the salesperson. I must however say that, by the time I took delivery, my experience did not leave me impressed. contact with the salesperson.

I ordered my new Porsche from Hennessy Porsche. My Sales Advisor is Grant Van Brewer. The experience was above and beyond my expectations, especially since I'm coming from a long time BMW customer. My Sales Advisor is Grant Van Brewer. The experience was above and beyond my expectations, especially since I'm coming from a long time BMW customer. My new Porsche is a 2022 911 Carrera 4 GTS. From designing to ordering and picking up it was an awesome experience. The finance was very simple and quick, no long drawned out time wasting like any other dealerships. I worked with Chris Velez and John Sargent, which they were great and helped me and answered any questions I had. The General Manager also was very friendly and for him attentions to detail was on top. When my car came in to get PDI, my Service Advisor is Dan Bush, he took care of some extra installations of different accessories that were not included in the PDI and made sure everything was done correctly. All in all my experience with Hennessy was unbelievable and of course I would recommend to anyone to come and buy their first or next Porsche from Hennessy. I am already ordering my next Porsche, the new GT3. Hennessy got me for life. Thank you. Eric Lopez More

The new service manager Steve Richardson is terrible. I brought my 2012 Porsche Cayenne in for service because of a check engine light and told them that another shop checked it and said it’s due to my cat brought my 2012 Porsche Cayenne in for service because of a check engine light and told them that another shop checked it and said it’s due to my catalyst converters. After service technician from Porsche did he’s evaluation Steve called me back and assured me it was not the catalyst converters and that it was something else which will cost around $3000 to repair. I asked Steve if he is absolutely sure it’s not due to the catalyst and he confirmed it was not. Them being a Porsche dealer I took he’s word for it and agreed to the repairs he recommended thinking they should have better technicians and testing equipment then the previous shop(I was very wrong). About 3 days after picking up my car from Porsche the check engine light was back and on top of that this time I started smelling a bad burning oil oder in the car too. Tried calling Steve right away but could never catch him(they would always have an excuse and transfer me to he’s voicemail which he never returned). Finally I called and asked for another service adviser (Charlie) who answered right away and tried to help. My wife dropped of the car for them to inspect it again and guess what they found the reason for the check engine light: “the catalyst converters” which I told them from the beginning caused the light..... By the way Charlie didn’t realize that the vehicle was worked on by them a few weeks earlier...and as soon as Steve found out that my car is back at the dealer and the diagnostic this time was what caused the problem in the first place, he immediately took over again (which I thought was very strange and suspicious). When I asked Steve what Porsche is going to do about miss diagnosing the problem the first time and charging me $3000 for something that did not fix the problem he said it’s a different problem and to fix it would cost me another $7700 🤯 and $1500 for the valve gasket to repair the oil smell that they caused. Long story short Steve Richardson along with Mark Ventei(general manager) did not even try to correct their mistake and left me with a broken car, check engine light, oil smell that I didn’t have before and a $3000 bill that was not necessary in the first place. The service department is awful and their technicians don’t know what they are doing if they couldn’t discover the correct problem the first time even after I told them the problem. After this incident I don’t think I would consider buying another Porsche for a long time and definitely not from this place because their service department is terrible!!! If you want peace of mind and a smooth service experience I would take my Porsche to a different dealer then Hennessy Porsche of North Atlanta👎🏼 More

Hennessy is my preferred Porsche dealership. They have always been honest and straightforward with me! I bought a couple of cars from their competitor in Atlanta many years ago but why do that when Hennes always been honest and straightforward with me!

So I've bought and traded exclusively with them for about 10 years now and I see no reason to change! And in sales, I appreciate Mike McPherson's knowledge and his enthusiam for cars, Porsche for sure...and others too! He's great to work with and he always follows up on his commitments! More
