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.

Great!
Great! Frank was on top of everything.They attended to a scratch on my car and now you barely notice it. Ben reset passwords. ☺️
Amazing performance car
When you buy a Porsche 911 you buy it because of its performance. My car now has 96,000 mile are runs and drives as it should. I do several DE track days every year. It has never let me down. It is amazing to drive, steers like it is on rails, stops on a dime, and goes as fast as I need it to go. What a great car!!

Second time back to Harper for service.
Second time back to Harper for service. First time was warranty a couple of months ago, no charge and they provided a loaner overnight. Today was 50,000 oil change and inspection. Only took a little over an hour and, as usual, Nick and everyone were super nice and got me taken care of. Two thumbs up, and of course, to Jack. Shannon has a great staff!
Best car ever
I am truly in love with my car. It has been incredible. Perfection is almost impossible but somehow Porsche did it. I think if you are considering this car just do it.

2006 Boxster Has It All!
I have owned old and new 911’s, including a 2004 911 Turbo, and my current 2006 Boxster Base with the silky smooth 5 speed manual has been the most fun to drive. Small, light, nimble, great exhaust note, etc. It’s just a well-refined, well-engineered and perfectly balanced roadster. I love it. My dad once said “The Germans will always be the world’s best toy makers, and he was right!”

Good with caveats
Bought 2023 Macan T. I traded in my aging 911 for it. I did not buy another 911 because they have become too big and expensive. The Macan T is a fun car to drive if you are actively trying to drive it. The back seats are tight. The PCM is frequently confounding or crashes and won’t play any media unless you stop the car, turn it off then open the door close the door and restart it. The fit and finish is excellent. The upgraded seats are good. I can’t activate the around view monitor unless I put it into reverse. The dealer wants 300.00 to connect the my Porsche app on iPhone to the car. Porsche corporate is helpful and has normal humans that answer the phone. The PDK is fun and the exhaust has some fun subtle sounding pops. It’s like a refined hot hatch car but not really a great highway car. The base stereo is plenty good enough. Styling is top notch. Adaptive cruise works but needs supervision while using. The rear wiper appears cheap and flimsy. Should have been mounted from the top of the rear glass. The guages in the day are too dark not lit up and hard to see. The back up camera has poor resolution and has a strange perspective making it less useful. It’s a fun, clever designed expensive car with tech flaws that you have to overlook to enjoy the car. If you buy a slightly used one from a Porsche dealer you can get your warranty close to 6 years. Service is expensive probably to pay for giving you a loaner.

Dr. Jeckyl - Mr. Hyde
Recently purchased the 2020 Macan GTS, so still in 'honeymoon' phase. That said, no issues to report. Pretty amazing how the vehicle can change personalities. Can be Dr. Jeckyl - smooth, quiet, refined touring car. Click a few buttons and its Mr. Hyde - growling, fast, quick steering tall hatchback that is ready for twisting roads or highway blast. Not encountered a vehicle that does this touring/sport change as well. Another standout for the 2020 is ability to go 'old school' buttons/analog - or modern digital interfaces. Like all the buttons, once you get to know them. Quick and less distraction from road. Rear seat is snug for anyone over 6 foot. Chose this over the Audi SQ5 - but it was a close contest. GTS wins on driving dynamics, but SQ5 is a wonderful luxury experience. Hard to resist the Porsche once you drive it. Does the luxury part pretty darn well too. Wow.

2022 Turbo GT
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

Purchased a used vehicle
Eric was my salesman and he was very helpful is closing the deal quickly and most importantly that worked in my budget. Arriving from out of the area he had the vehicle ready to show upon my arrival. USI Motors will definitely be my first choice for my next luxury vehicle.

3rd time to buy here...
And will again in the future. We have always had great experiences with this honest, family run business. This was our first time to trade in on a vehicle here and feel like we got a fair price and a great value in the new car.
I turned in my BMW for a Porsche Cayenne
I purchased my Porsche Cayenne in January 2023. I am very happy with my purchase; the team were professional and knowledgeable. Will buy again. Satisfied.

Lexus of Knoxville, TN
Walter Hoover-our sales person was very knowledgeable, which made our experience purchasing a new 2023 Lexus GX 460 easy and fast. I highly recommend Walter Hoover and Lexus of Knoxville.
Beautiful and very fast!!!
I owed a 2010 Cayenne GTS and thought that SUV was awesome. Porsche has really stepped up their game. The 2021 Cayenne GTS is very stunning and drives like a 911. Extremely happy so far!!
