The Porsche 911: A Certified Pre-Owned Icon, Verified Before It Reaches You
A Porsche Approved 911 gives Roswell buyers the car that defines the brand, already reviewed against its own certification standards before it's offered for sale. Our Certified Pre-Owned 911 inventory typically spans the range, from the Carrera S through the track-focused GT3, so the question isn't whether the car has been checked out. It's which 911 fits how you drive.
Every listing on this page includes mileage, previous owner count, equipment, and full pricing detail. That level of specificity matters with a car like the 911, where trim, drivetrain, and options change the character of the vehicle as much as the model year does.
Why Roswell's 911 Buyers Trust Hennessy Porsche North Atlanta
Hennessy has represented luxury vehicles in metro Atlanta for more than 50 years. That tenure carries into how the Porsche Approved program is handled here, with every Certified Pre-Owned 911 reviewed by Porsche-trained technicians rather than general used-car staff.
Our sales team works exclusively with the Porsche lineup. Questions about GTS T-Hybrid architecture, GT3 drivetrain options, or Turbo S output get answered by people who work with these cars daily.
The Roswell showroom on Mansell Road is built around the ownership experience, not just the sale. From the lounge to the service drive, the standard is set to match the car.
The Porsche 911: From Carrera S to GT3, Verified Trim by Trim
Trim range and drivetrain.
Our Porsche Approved 911 inventory typically includes the Carrera S and all-wheel-drive Carrera 4S, the Carrera GTS, and the naturally aspirated GT3, with Turbo S and special-edition models available as they come through certification. Drivetrain varies by trim, with rear-wheel drive on the Carrera S and GT3, and all-wheel drive available on 4S, 4 GTS, and Turbo S variants.
Performance highlights.
Recent Carrera S models produce 443 to 473 horsepower, depending on model year, from a twin-turbo flat-six. The current Carrera GTS adds the Porsche T-Hybrid system, a 40 kW electric motor built into the PDK housing paired with an electric turbocharger, for a combined 532 horsepower. The GT3 keeps things naturally aspirated, with a 4.0-liter flat-six producing 502 horsepower and revving to 9,000 rpm, available with either a 7-speed PDK or 6-speed manual transmission.
Technology and cabin.
Every 911 we carry includes Porsche Communication Management with a 10.9-inch touchscreen, wireless Apple CarPlay and Android Auto, and a digital instrument cluster in front of the driver. Individual listings note additional equipment such as Sport Chrono Package, Sports Exhaust, Porsche Active Suspension Management, and Burmeister or BOSE audio, since these options vary unit to unit.
Trim highlights.
The Carrera S favors a broad, everyday performance envelope, quick enough to satisfy without demanding a track day to enjoy it. The GTS splits the difference between daily usability and outright pace, and the T-Hybrid update sharpens throttle response without changing what makes a GTS feel like a GTS. The GT3 is the outlier of the group, built around a naturally aspirated engine and a chassis tuned for track use first and street use second, for buyers who want the closest thing to a race car that still carries a warranty.
The Porsche 911: Certification That Goes Beyond a Walkaround
A Porsche Approved 911 completes a factory-defined 111-point inspection covering body and paint, drive system and underbody, fluid levels, interior systems, and a road test that checks braking, handling, and driver assistance functionality before it earns the Porsche Approved seal.
Certification also brings the Porsche CPO Limited Warranty and 24-Hour Roadside Assistance, with a CPO+1 Vehicle Service Contract available for buyers who want coverage extended further.
Vehicle documentation is reviewed as part of that same process. Maintenance and warranty records are checked for completeness, so the ownership history behind a Certified Pre-Owned 911 is as verifiable as the mechanical condition it was inspected against.
Financing and Leasing a Certified Pre-Owned 911
Our finance team works with a range of lenders to structure a Porsche Approved 911 purchase around your timeline, not a one-size-fits-all rate. Start the process before your visit through our finance application, or speak directly with our Finance Center team about current terms and available lenders.
If you're replacing another vehicle, a trade-in can offset the cost of your Certified Pre-Owned 911 directly. Value your trade-in online for a Kelley Blue Book-based estimate before you come in, so pricing conversations start with real numbers instead of guesswork.
Leasing a Porsche Approved 911 is also available for buyers who prefer lower monthly payments over full ownership. Our team can walk through lease terms alongside traditional financing so you can compare the real cost of each path side by side before you decide, whether you're looking at a Carrera S or a GT3.
Porsche-Trained Service for Your 911
Our Roswell service department is staffed by factory-trained technicians who work on 911 platforms as part of their regular routine, not as a specialty add-on. That includes GT3 and Turbo drivetrain service, T-Hybrid system diagnostics on the current GTS, brake service, tire care, and the software updates that keep 911 model systems current.
Every service visit uses Genuine Porsche Parts to keep your 911 aligned with factory tolerances. Schedule service online, or check current service specials before your next appointment.
