Even though the Boxster was designed as a convertible an open top car is generally more flexible than a closed top car, when the unit body flexes a little over the bumps, something rubs a little bit and causes a squeak. You can also step on the gas or turn up the radio, or both!

Have noticed that when I step on the gas and turn up the radio the sound goes away. It's a Miracle!!!
