Love this dealership!
Love this dealership! The new location is wonderful - I send my family here. My brother bought a car, and loves it!
100% a Porsche
I purchased the GTS. Very comfortable, sporty and fast. Good range. No range anxiety. Wish I hadn’t waited so long to get one. 100% a Porsche.

Exceptional Customer Care
The level of service and professionalism Josh provided far exceeded my expectations and it made my first Porsche experience very memorable. He did an exemplary job of explaining to me everything I needed to know about Porsche, the Macan and the options offered with the various trim levels. From day one, he never made it about selling me a car, but rather finding the car that was a perfect fit for me. After working with Josh for close to nine months, I took ownership of an amazing Macan S. I couldn’t be happier about the purchase and overall experience!

Just wanted to say thank you again to Devin (hope that’s
Just wanted to say thank you again to Devin (hope that’s spelled correctly), Nick, and Dominique. I think I bought the least expensive car on the lot (used Honda) and honestly they all treated me like I was buying a new Porsche off the showroom floor. I always dread the car buying experience, and just coming off a terrible experience with another dealer, they all far exceeded any expectations. A+ all around.

Excellent service.
Excellent service. Approved immediately. Thank you, Peter, for your help! There are many options to choose from.
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

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.

Pepper was very helpful and professional.
Pepper was very helpful and professional. I would recommend this dealership because of him. Very pleased.
Too expensive to fix without insurance
Great until the extended warranty ran out And 2023. Cost of replacing a valve and associated work was $5000. Shakes if rear windows open from wind. Aerodynamic so so.
