06 MCS 120k, was doing some spring cleaning and lifted the carpet in the trunk to find out the extreme right (passenger) rear corner of the unibody had cracked or perforated or separated (however you want to put it). There is no rust that I can see, it looks like a stress crack in one of the seams of the unibody. It's not that long but I can see light through the crack.

I have a 120k miles, anyone know my options here before I contact the dealer?

I'll post pics later tonight, wife has the Mini.

Thanks for any/all advice.
