Is the Porsche 718 Cayman GT4 a good investment?

The thesis

The first Cayman to receive GT treatment: 3.8L naturally aspirated flat-six (385hp), mandatory six-speed manual, GT3-derived chassis. Originally $85k, now averaging $94k and climbing—up $10k in 12 months per Classic.com. This is the last naturally aspirated, hydraulic-steering mid-engine Porsche before turbocharging. Scarcity (~2,500 built globally), Motorsport pedigree, and recent acceleration signal early-cycle momentum.
