The three GT2 and GT2 RS generations differ not only mechanically but in where they sit in the market and how they have performed:
997.1 GT2 (2007-2009): The 997.1 GT2 was conceived as a high-performance version of the 911 Turbo, but with rear-wheel drive rather than four. It was less extreme than the later GT2 RS cars and less tightly limited. Character: the last of the plain GT2s without the RS suffix, striking a balance between everyday usability and extreme performance. Values: after the early fall, prices are now steady to rising, and it has passed its low.
997.2 GT2 RS (2010-2011): With the RS suffix Porsche presented a more radical GT2 for the first time: lighter, more powerful and single-minded about performance. The strict limit and the final use of the race-proven Mezger engine make it a sought-after collector car. Character: purist in approach, focused on weight saving and outright performance, yet still with a manual gearbox. Values: an almost continuous climb since production ended, already roughly 67% above its list price when new.
991.2 GT2 RS (2017-2019): The 991.2 GT2 RS marks a technological leap: the first with the PDK gearbox, at 700 PS the most powerful production 911 ever built at the time, and equipped with the latest racing technology. Character: outright performance combined with the most modern engineering, less purist than its predecessors but hugely capable. Values: an extremely strong climb shortly after production ended, above all during the pandemic, with mild corrections since 2022/2023, though still well above the original list price.
