Is the Porsche Cayman (981) a good investment?

The thesis

The 981 GT4 is the last naturally aspirated 3.8 flat-six Cayman, lauded as one of Porsche's finest driver's cars. It won evo Car of the Year 2015, beating the 991 GT3 RS. Prices have corrected from the £100k+ bubble to £55–75k, settling below original £64k list. With 718 GT4 (4.0 turbo) values also softening, the 981 now offers eCoty-winning performance for less than a new Alpine A110. Cycle position is early; the repricing creates genuine value for long-term holders.
