Is the Porsche 911 GT3 a good investment?

The thesis

The 997.2 GT3 is the last Mezger-engined GT3 and offers 3.8L flat-six NA purity with a proper six-speed manual. European market data shows examples clustering €130–180k, translating to £110–155k+ in the UK. It sits below the more expensive 991.2 GT3 manual but above base 997s. The Mezger engine is legendarily robust and the manual makes it a driver's car in an era when even GT3s went PDK-only (991.1). Strong Porsche GT liquidity and the last-of-Mezger narrative support mid-cycle appreciation potential.
