Is the Porsche 911 R a good investment?

The thesis

Limited to 991 units, the 911 R pairs the GT3 RS 4.0L naturally-aspirated flat-six with a six-speed manual in a lightweight, touring-focused package—no rear wing, purist ethos. Original £137k, current UK market circa £280–360k. It is the 991 generation's manual swan song, an instant collector piece. Mid-cycle but fundamentally scarce and perfectly aligned with the brief: rare, manual, naturally aspirated, limited special edition.
