Hate to bump an old thread, as I'm probably missing something simple.
How do you use the latch? I've tried pushing on it and pulling on it. Looking at it, it even seems like it could slide to the side.

I don't want to break anything, so any assistance is welcome.
I really want to get this e55 back on the road. It's been sitting in a nice climate controlled garage for two years now, but it deserves to see the road.
