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.
MY SECOND CAYENNE
My first Cayenne S was a 2004, which we loved - this is a tremendous upgrade in every aspect. The 2019 is terrific in every detail!

Thanks to my salespersons Trey and Derek, I had an outstanding experience purchasing my Porsche 911 Carrera. They were incredibly knowledgeable about the Porsche lineup. Their professionalism and dedication made the entire process smooth and enjoyable, from the initial inquiry to delivery. Communication was prompt and thorough, ensuring I felt confident and well-informed every step of the way. I highly recommend their service to anyone looking to buy a Porsche. Sent from my iPad

Purchase 2016 Mercedes Metris passenger van
Bennie Barcroft was extremely helpful and supplied me with any information needed. He even picked me up at the airport when i flew to Knoxville to pick up the Metris. The Metris is a great vehicle. I am sorry Mercedes has chosen to drop the model from their U S product line.
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.

Katie Thompson was a fantastic salesman ?
Katie Thompson was a fantastic salesman ?! She helped me not just get a new work truck after my car died, but she helped me transfer all my tools over to the new one. She had a lot of knowledge about each Toyota vehicle, especially the Tundra's! My new truck is exactly ? what I needed for my handyman business ?! Gary at financing was a big help too. He QUICKLY adjusted what needed to be adjusted and helped me choose the correct financial options for my Tundra! Thank you, Toyota of Knoxville!!

Macan Turbo - Wow of an SUV
Love Love Love my 2021 Macan Turbo - It tracked almost as good as my 2019 Boxster GTS. (Within a couple seconds). Tech features are great - love the PCM (Radio Module - easy carplay and works well). Very comfortable suv smooth riding. Seems very reliable so far. 15k miles so far.

Was very pleased with te service I received from the company and plan on doing business with them for many years to come.also. They are very helpful.
Best car I ever owned
I have a Panamera 4 and it is the best car I have ever owned. After 5 years it has never let me down- not even once- and besides the recall notices that were always handled during regularly scheduled visits nothing has needed attention. The fit and finish and styling are still totally on point after all this time. The car looks and drives exactly like it did when new despite 30,000 miles. Also, I have 21’ wheels and thought I would have to replace the tires by now. However, they are chunky and full of tread. I drove 1000 miles in one day last week averaging 77mph and 29.5mpg. Great performance and a long drive in one day. It was so nice on the road and my body despite the longest drive of my life! Fit and finish, quality of the components, and tech that is totally up to date after 5 years. Wow. Loved it! I also own a cayenne and a 2015 Mercedes S class. The Mercedes is not close to the quality unfortunately.

Purchased 2007 Jaguar XKR
Eric and his staff fulfilled all my request concerning my purchase in a very timely/ professional manner. Car was delivered on schedule to my residence. I am very happy with my purchase and USI. Motors.
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.

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.
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!

Great Experience
I had a really awesome experience buying from these guys! I had been in the market for a SUV and found the right one with US Auto Network. There vehicles are very clean and well taken care of and you can tell these guys take pride in what they do!! The SUV I bought had a problem soon after purchase and so I told them and they sent me to the shop right away to have it fixed with no problem. These guys treat you as if they have been knowing you forever. There location can be discouraging because of the other dealerships around but definitely don't be discouraged because these guys are nothing like any of the other dealerships. My wife's next vehicle will be bought here for sure and I will be encouraging any of my friends and family that are in the market to go here!! Thanks US Auto Network for such a great car buying experience and friendship!!!

Excellent Customer Service
My experience with Bennie Barcroft was excellent. He answered all my questions quickly and put together a quote that was detailed and transparent. He was quick to answer follow-up questions and it was a pleasure to deal with him. I ended up not ordering a vehicle at this time due to high interest rates but will contact him first when I decide to do so.
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.

car is great, great salesman, delivered on time. #
i bought this car over the phone, my salesman was nick and he was a honest person. he was a big help in me buying this car. i would do it again with him. i love the car and will keep it for a long time. if you want a honest sales person, then call and ask for nick.
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.
