Depreciation Insight

Like most high‑performance sports cars, the Porsche 911 GT3 [991] experiences a unique depreciation curve. Industry data and expert analysis indicate typical patterns:

  • First year: 15‑20 % drop from the original invoice or retail value
  • Year two: 10‑15 % additional decline
  • Years three to five: 5‑8 % annually, stabilizing around 40‑50 % of the original price by year five

Several factors influence these rates:

  • Condition: Road‑ready, low‑km, and original‑to‑factory (OTF) options can retain more value
  • Trim: The GT3’s aspirated engine is highly sought after in the used‑market; exotic variants such as the 991.2 may price slightly better
  • Service history: A clean title and factory‑certified service records reassure buyers and often justify a higher asking price

When evaluating whether a used Porsche 911 GT3 [991] is a worthwhile investment, these depreciation trends can offset the higher upfront cost, making the model a strong contender for break‑even or even slight gains over a 5‑year ownership span.
