I am suffering from an annoying resonance in the cabin of my Cayman. It's similar to the resonance in some four door cars when a rear window is down - a deep buffering sound that presents a cyclic pressure that feels as though it is vibrating through your head!
I've read a mail from Rumba who also appears to be suffering this - is this a common problem and has anyone found a cure?
