Is the Porsche 911 GT3 a good investment?

The thesis

After the 991.1 GT3 went PDK-only, outcry from purists led Porsche to reintroduce the manual in 991.2 (2017–2019), available on standard GT3 or Touring variant. The 4.0L naturally aspirated flat-six, manual gearbox, and last pre-992 GT3 position it as a modern classic in waiting. Recent market data shows strong demand and tight supply. Prices sit high end of your budget but represent the most modern naturally aspirated manual GT3 available. Low-mileage Touring examples will command premiums.
