The Cayman S is built on the excellent mid-engine Boxster platform but has a much stiffer structure, more HP & Torque from a better revving engine, and a modified, stiffer suspension.

Being based on the Boxster it pretty much is equipped the same way. The US model comes standard with leather seating surfaces and upgraded sound package.

If you like the "standard features of a convertible" aspect....slower, more body flex, less sharp handling, but an open top, the Boxster S is a great choice and cheaper than a Cayman. It's all up to you on what is important.
