Willing to work with you.
Willing to work with you. Corrected issue post sale with no hassle. I’d buy there again.
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!

Excellent service!
Excellent service! They made car buying quick and easy! No pressure sales. They have great cars on the lot!
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.

Anyone there doing his best to satisfy the customer I was
Anyone there doing his best to satisfy the customer I was definitely recommended anyone to go there for shopping.
I spend about $1000-$2000 each year on maintenance.
I spend about $1000-$2000 each year on maintenance. One may consider that high, but I purchased a 911 C4S car for $35,000; the MSRP was $93,000 in 2004. The vehicle has appreciated since 2019, and now, with such a detailed service history over the years, it could sell for $40,000. So you either pay in depreciation or maintenance, and though I may be a stickler for maintenance, it keeps the value stable. I could have gotten a new Camry for $35,000, but it would be worth about $15,000 now and less fun. Next car I will jump up to a 2012 to 2015 Porsche. You can't go wrong if you get the right model, rare options, and even rare colors. Number one is having complete maintenance records; don't buy one without them.

Dealership was incredibly responsive to my inquiry - they were really great to work with. I ended up buying a car elsewhere, but J&S Autohaus was a pleasure to deal with.

Just got a 2019 Carrera 4 GTS. Seems great so far, very fast and handles great. GTS model seems to be the best bang for the buck as far as power and options that are included

Highly recommend, Great dealership!
Great experience buying a beautiful Camaro from Carnu! They were honest, friendly, knowledgeable and gave excellent communication being I was out of state. Turn key deal getting the car shipped to my door. I would buy another car from them in a heartbeat! I had a small issue when the car arrived (the battery was dead) tried to charge it but it was not charging…I let Anthony know not thinking they would have to do anything just an FYI…but he said “get a new one and I will cover it”. He kept his word! Thanks Carnu for a great Car and working with me on price!
There truly is no substitute for Porsche
I've raced Porsches including GT3 Cup but this is my first street Porsche. My wife and I love convertibles for touring and I wanted a track capable car, too. A 911 will likely be next but I am really glad I started with my 718 Boxster GTS. The turbo four cylinder is outstanding with great power, especially down low torque, and we're seeing excellent fuel mileage. Some purists say it has to be the flat six but this car proves them wrong. I don't mind the sound at all, it reminds me of a wonderful air cooled Porsche. Love the performance, comfort and utility (two trunks!) of my 718 Boxster GTS and can't wait to get it on the track soon, too.

I have had my '02 base 6 speed manual Carrera Coupe for
I have had my '02 base 6 speed manual Carrera Coupe for about 5 years. It was a car I had checked out, but my wife bought for my 50th. I love the car. I do some "spirited drives" with a great group of folks early Sunday mornings (when the back roads are pretty empty). The car is just a blast to drive hard. I have never come close to finding its limits in terms of cornering. It can be driven quite sedately if you keep it under about 4,000 RPMs. Fine around town. Stop and go traffic is obviously a pain with any manual car, but the clutch is a little stiffer than, say, a Honda. Road trips are fine if you can fit, and it's a bit noisy on the highway from tire noise. I was interested in the 911 over a used Cayman (or Miata, etc.) because I can put my kids in the back (they are 4 and 7, and they LOVE pulling "g-forces" The main downside is this is a 22 year old car with a list of things that really need to be replaced. Not because they are broken, but just standard maintenance. I need a transmission rebuild to fix an occasional issue with 2nd gear. Rear main seal. Check the IMS bearing. Water pump. Then the suspension and engine mounts probably need to be gone over. All this is probably $12,000-$15,000. Bottom line, these 996 911s can be had for mid-20's, but it's still a Porsche. You don't get Honda-priced parts when you need to replace something.

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.

Traded my old sedan for a crossover.
Traded my old sedan for a crossover. They gave a fair trade-in quote and clearly explained how they calculated it. No pressure to finance through them - I was free to compare. In the end, I got both the car and loan here. No surprises in the contract.
