Not to be confused with: GT3 RS (992) — 525 hp, active aero (DRS), track-focused GT3 Touring — without rear wing (retractable spoiler), more discreet GT2 RS (991.2) — turbocharged (700 hp), greater straight-line performance 991 GT3 (predecessor, 500 hp); 992.2 GT3 (successor) → high-revving naturally aspirated flat-six (≠ 911 turbocharged)

Collectability & valuation

Rarity

series production, but highly sought after; manual, Touring, PTS colours and GT3 RS particularly desirable

Desirability

9 000 rpm naturally aspirated flat-six, benchmark dynamics, direct motorsport lineage; original specification, low mileage, Porsche service history are decisive; values remain firm

Points to watch

track use (wear), high-revving maintenance (clutch/tyres), costly ceramic discs; originality (options, PTS); full service history

Valuation

on request (price range + comparables + sources + date; manual/Touring premium)
