Is the Porsche 911 GT3 RS a good investment?

The thesis

The 991.2 GT3 RS (520 hp, 4.0L NA flat-six) represents the final 991-generation RS and is now out of production. With 4,750 units globally, it's relatively accessible yet track-proven and naturally aspirated. UK valuations average £158k, well below your budget floor, but top-spec, low-mileage examples reach £250k–£315k. Strong Porsche GT liquidity and the 991 chassis is the last before the 992's added weight and size.
