Is the Porsche 911 (997.2) a good investment?

The thesis

The 997.2 GT3 RS 3.8 delivered 444hp from its Mezger flat-six—a motorsport-derived unit revered for strength—and came exclusively with a six-speed manual. Only 1,619 built globally for 2010–2011. It sits between the earlier 997.1 RS and the ultra-rare 997 GT3 RS 4.0 (600 units, now £400k+). This 3.8 has not yet run hard; UK prices sit £100-150k while the 4.0 has appreciated sharply. The Mezger engine's cachet grows as turbocharged GT cars dominate the new lineup, positioning this as a 'last analogue RS' buy before six-figure appreciation begins.
