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.
Just gorgeous
What can you say about any 911? The one I test drove was the S. It’s just the perfect sports car. Light, just enough power to go fast, not overwhelming. Comfortable, quiet, composed at any speed. The soft top is so quiet. Almost like a regular top. With the top down, you can still hold a somewhat normal conversation at highway speeds. Just the perfect car for a cruise or fast run on a sunny day.

looking for a rx350 lexus good selection
excellent response and ordered a car from nashville location good selection , no pressure and answered all our questions would recommend this location to a friend or relative
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.

Good fair deal.
We purchased a Jaguar from USI. We feel we got a fair deal and the salesman Eric was professional and personable. We would do business there in the future.
INCREDIBLY Beautiful Car!
Words do not do it justice. This car is simply stunning visually, growls delightfully, and it's a dream to drive, incredibly responsive and shifts so smoothly. After a lifetime of exceptionally cool/classic/prizewinning cars - I do believe this one will turn out to be my all-time favorite. My apologies to my Jaguar clubs!

We just purchased our second vehicle from USI Motors
We just purchased our second vehicle from USI Motors Sales Agent Nick Compton knows his cars and the other guys actually work together for your best customer experience! Well, done guys, 5 out of Five starts from us! :)
Run, don’t walk. Buy this car!
Not a daily driver. But, by far the most fun car I’ve ever owned. Bought a 2013 S MT in 2015, still can’t part with it in 2024. This one’s a keeper. It is a pure joy to drive, mostly top down but even top up, the flat 6 boxer engine sound is incredible. Handling is superb - it’s like the car is an extension of the person driving it…the car goes where ever you want it to go effortlessly and nimbly…it’s amazing! The 981s MT is an incredible value. One of the best purchases I’ve ever made.

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 think most of people here have not driven a Macan 3.
I think most of people here have not driven a Macan 3.6 Turbo engine with 400+ HP. This car is amazing you can't compare this one with other lower Macan models. this is the one to have.. We owned several Porsches including Cayennes turboS. This is a compact daily driving machine with Lot's of power and is fully loaded. The turbos 3.6 cost over $100K after taxes for a reason , Please don't compare this model with other low built Porsches for middle class, this is a High End Vehicle for a reason ...maybe the same as compare the Boxer with a 911 Turbo S.

I would highly recommend this car place to anyone
They had everything for us and super great to work with us. And told us everything we needed to know about the car that was great. The car drove very well and everything worked. The price was good and the car was clean. The car is a very decent size car and it has a 2 year warranty too.
Most fun yet practical car
I have had 3 Boxster s over the years and this one for over 10. Loved every minute driving it. Great pick up and handling plus two trunks to allow for hauling things. A real head turner. Just need to maintain it for it to keep running well. I'm only selling mine cause we moved down a dirt road and its too rutted for a sports car. I got it for a great price, so letting it go for thousands less than it's blue book.

From my first friendly texting communication with
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.

Great used car buying experience
Bought a used BMW from NAW and I would definitely recommend this place to friends and family. The cars I looked at were quality and all fair priced. The process was straightforward with no gimmicks. The price was excellent for the car I bought, and the staff made me feel taken care of throughout the process. I’ve been to many other large and small dealerships and NAW is among the list of dealerships I will go to for future used car purchases.
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.
