Is the Porsche 911 a good investment?

The thesis

The 997.2 GT3 RS 3.8 represents the last of the Mezger-engined GT3s and remains a purist touchstone before Porsche went fully PDK and turbo. With 444bhp naturally aspirated flat-six, wide body, and manual-only, it sits between the now-stratospheric 4.0 (£400k+) and the cheaper 997.1 RS. Recent data shows values stable at £180k–£250k depending on spec. As the marque's analogue GT era closes, the 3.8 offers meaningful upside without the speculative bubble of newer models.
