The Porsche 911 is one of the best cars in the world for holding its value. In iSeeCars' 2026 study of more than 950,000 five-year-old cars, only one model lost less: the 911's smaller sibling, the 718 Cayman.
An average hides a wide range, though. A base Carrera, a Turbo S and a GT3 are very different propositions on the used market.
Key numbers
- 5-year depreciation
- 11.1%, according to iSeeCars' 2026 study. That's about $15,500 below the sticker price.
- Rank
- Second-best of all vehicles, behind the Porsche 718 Cayman at 9.6%.
- For comparison
- The average car loses 41.8% in five years.
- Biggest variable
- The exact car. GT models and manuals can sell for more than they cost new.

From iSeeCars' 2026 study of five-year-old cars sold between March 2025 and February 2026, checked October 2026.
The study also shows the wider used market strengthening: the average for all cars improved from 45.6% the year before.
Why the 911 holds its value
- Demand outruns supply. Porsche limits production, especially of GT models, and many buyers wait for an allocation.
- The design changes slowly. A five-year-old 911 still looks and drives like a current one.
- It has an enthusiast market. Buyers know exactly which options and versions they want, and they'll pay for them.
- It's usable. A 911 can be driven every day, so the pool of buyers is wider than for most sports cars.
Which 911s hold value best
- GT cars. The GT3, GT3 RS and GT2 RS are built in limited numbers and often sell above their original price.
- Manuals. A manual gearbox carries a premium on most versions that offer one.
- Special colors and options. Paint to Sample colors and sought-after options add to resale.
- Coupes over convertibles. iSeeCars' model-level estimates show the coupe keeping more of its value than the convertible.
Older 911s follow different rules. On 996 and 997.1 cars, value depends on engine history, including the IMS bearing and bore scoring. Air-cooled cars are collector items priced on originality.
Do other Porsches hold their value?
The sports cars do. The 718 Cayman is the best of any car in the study, and the 911 is second. Porsche's SUVs, sedans and electric models are priced more like other luxury cars, and electric vehicles as a group lost 57.2% in five years in the same study.
So "Porsches hold their value" is true of the 911 and the 718. For a Cayenne, Macan, Panamera or Taycan, expect the depreciation of a luxury car, softened by the badge.
What it means when you sell
A car that holds value this well deserves more than a single trade-in quote. Dealers know 911s sell quickly, and offers vary. Collect at least two or three, and for a GT car or a manual, add an enthusiast auction estimate.
