  Carrera and Carrera S — the market anchor; why the S premium has narrowed and what it means for entry-level 997 buyers

• —

  GTS — factory wide-body, 408 bhp, hydraulic steering: one of the most complete 997s and still under-valued relative to the GT cars

• —

  Turbo and Turbo S — the VTG turbocharger story; Gen 1 vs Gen 2 power and specification differences, and the Turbo S premium case

• —

  GT3 and GT3 RS — the Mezger-engine cars; Gen 1 RS rarity, the 997.2 GT3’s DFI controversy, and the specific chassis numbers the market prizes

• —

  GT3 RS 4.0 — 600 cars, no options, the last pure Mezger road car; why it now trades above GT2 RS money and where values are heading

• —

  GT2 and GT2 RS — the widowmaker succession; rear-drive 530 bhp, ~1,000 cars, and the growing scarcity premium relative to the GT3 RS

• —

  Exclusive and special editions — Sport Classic, Speedster, Black Edition: the collector case for low-production variants in a high-production generation

Buying & ownership

• —

  DME over-rev reports — how to pull them via PIWIS, what the logged data reveals about a car’s history, and when a single event is cause to walk away

• —

  Borescope inspection protocol for the 3.8 and 3.6 flat-sixes: the cylinder wall patterns, the bearing surfaces, and what each image tells you

• —

  The Porsche buying paper trail: Certificate of Authenticity, options list, PDK stamp, service history — what’s verifiable and what isn’t
