From my first friendly texting communication with Chandler, to the ride they graciously provided me from the airport (thanks Ben!), to Derek’s expert tutorial on how to operate the cockpit’s knobs and buttons—and especially the genuine “excited for you” spirit that they all exuded as they sent me off into the world in my first Porsche—my experience with Harper Porsche in Knoxville has been first rate. Ideal. Everything I could have hoped it would be. They are very responsive, efficient, courteous, knowledgeable, and trustworthy. And the single owner, practically mint 2016 Porsche Panamera 4 Edition they sold me? It’s the most gorgeous thing on the road.

Great Experience.
Great Experience. My son was searching for a car and he found his dream car with Harper Porsche. I inquired about the car and spoke with Trey. From the beginning of the conversation, I knew this was the place and the salesman that I was looking for. After the test drive, Trey stayed in contact with my son and I until the end. Let's not forget about Jennifer in finance. She was, also, very knowledge and walked us through each steps of the purchasing process. If I could give them 10 stars, I would. Thanks for making my son a happy.
Quiet Ride
Quiet ride, better fuel economy than on window sticker. Center console controls are mind boggling. More storage nooks would be helpful. Owner's manual in 8 point type not very helpful.

Turbo GT. Hard to believe it drives as well as my 911 through the mountains. Ride is better than advertised with the lowered ride and stiffer suspension. PTO color is flawless. It does not drive around corners…it deletes them

Jonathan worked tirelessly to find the car I wanted with
Jonathan worked tirelessly to find the car I wanted with exactly the options I wanted. He is incredibly professional and realllllly knows his stuff about cars. My car was flawless other than a small leather scuff, which he showed me within the first few minutes of our interaction. HIGHHHHLY RECOMMEND!
More raw performance feeling than latest model
My GT4 is the most fun car I’ve ever owned, and I’ve had multiple BMW ‘M’ cars. As someone else mentioned, not a drag car although 4.1 secs 0-60 is no slouch. It revels in cornering, I’ve often said “I’ve never met a corner I couldn’t go around faster the next time”! I’m 6’5” and apart from being a contortionist getting in and out, it’s dry comfortable for me once sitting in the carbon fiber buckets.

Look no further for high quality, fun, used SUV
Purchased a base Cayenne as a CPO from a local Porsche dealer in 2022 with 34,000 miles (this is my 6th Porsche). Better than any other SUV I have ever owned by far. Fun, reliable, and great looking. And a great deal.

A very sweet ride
This review if for my ‘13 911 Cab(a very sweet ride); which I purchased as a two year old certified Porsche; which I just traded for a new ‘22 911S Cab, an even sweeter ride!! The only reason for the 4 for value for the money, these cars are very expensive, but for a young 78 year old guy just a great car if one can afford them.
