Is the Porsche 911 GT3 a good investment?

The thesis

After Porsche deleted the manual on 991.1 GT3, enthusiast outcry brought it back for 991.2 with 4.0L flat-six and 500hp. The manual take rate was high, ensuring better supply than 997 RS variants. At an average £158k (converted from $197k USD) these sit perfectly in budget and represent a more modern, faster GT3 that has not yet experienced the stratospheric run-up of 997 RS or GT3 RS 4.0 pricing. The 991.2 manual GT3 is early in its appreciation cycle.
