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.
What can I say, the benchmark of sports cars.
What can I say, the benchmark of sports cars. I have a 4S Cabrio. I chose the 4 as I like all-wheel-drive, even in Florida. Better grip. The S also has more horsepower. Build quality and fit and finish our superb. The ultimate sports car without all the problems of the Italian cars. You’d be hard to find a car with better handling and Performance. The look is timeless. There’s no mistake at what you’re looking at when you see a Porsche. 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.

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.

Great company and service! Top notch!!!
No need repeating what is on their website, that’s exactly what you get when you use Overton Automotive Brokers. Could not have been easier. Jonathan was great, he really knows his cars.
The perfect sports car
I researched 911 vs 718 for almost two years. I drove a Carrera 4S at PECATL and loved it, but I wanted to keep my budget lower. A base 911, while a great car, just did not live up to the 718's nimbleness with its mid-mounted engine. I was lucky with my find - a GTS 4.0 It drives perfectly. The storage is ample enough for a large check-in suitcase up front. You also have the rear trunk. This can be a great daily driver with next-to-nothing for maintenance aside from regular oil changes and routine maintenance check-ups. I've put close to 4k miles and it is a special occasion each time I get in.

Lexus of Knoxville is simply the best . Great vehicles. Friendly, knowledgeable and courteous personnel.
Even better than my excellent S2000
Terrific car and the best I have ever owned Comfort downgraded because the leather seats are just too hard, a common problem with leather seating. Lexus uses much softer leather, making their seats much more comfortable for a long drive. Wouldn't need heated seats if not for the leather seating surfaces. Fabric is MUCH more comfortable. Interior design is excellent except for the extensive use of bright metal accents which should never be used in a convertible. Solved with matte black vinyl wrap. Infotainment system is an unmitigated disaster - it simply fails to work much too often, specifically Apple CarPlay works only about half the time, backup camera often fails to display, and sometimes the display shows nothing but "Loading Home." This should be simple to fix but local dealer refuses or is incapable of doing the right thing. This is a terrific $50K sports car; too bad it costs so much more. Reliability downgraded only because of infotainment problems. No mechanical issues.

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!”

Rocket on four wheels.
This car is a rocket on 4 wheels. The PDK transmission shifts very quickly with no lag or delay in torque. In fact the torque seems to increase in addition to achieving great gas mileage. That's a formidable task compared to other performance cars. The car does sit low to the ground so if you have bad knees or hips then it might not be a good fit for you.

Had a good experience with Grayson MINI of Knoxville.
Had a good experience with Grayson MINI of Knoxville. They have the best selection of used cars that I have found in town. Everything was easy and we are happy with our used Silverado that we purchased last week.
Expensive and worth it.
I bought my 2021 GT4 in January of 2021 and have put 14,500 miles on it since them. I have tracked it at Mid-Ohio, Pitt Race and Nelson Ledges. We have driven to California and Florida from NE Ohio. I am 69 years old and find the car to be quite comfortable for long distance trips. Is it expensive? Yes. Is it worth it? YES!

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.
