MSRP: $80,850 / $82,950. Has anyone ever lost money collecting Porsches? Probably, but the new-for-2018 higher-performance versions of Porsche’s standout mid-engine Cayman coupe and Boxster roadster (shown above) models would seem to be welcome additions to any collection. They command a stiff price, but they’re still more affordable to purchase than even a base version 911, and are arguably as much (or more) fun to drive.
