Open Question: How long has your C-class driver's seat been squeaky for?

I've got an '05 C230 thats got the most awesome squeak in the lumbar support whenever you hit a good wrinkle or bump in the road. How about yours?

 

I got one too! 03 C320. At first it drove me nuts, but I'm used to it now.

 

My only squeek comes from the console/seatbelt contacting each other. I put a piece of felt on the rub spot and it is cool now.
