Thanks Dave. So without backseat folding down, can you still put a cello in the trunk?
I've loaded up to 3 guitars (or equivalent stringed things) in the back easily. With one seat dropped, I've loaded an 88-key weighted keyboard in the back, sticking thorugh the pass-through, then loaded a guitar and a couple of other instruments, plus electronics bags in the back as well.
[edit] Just remembered that I've also loaded a cello and guitar in the back with one seat dropped -- the cello neck went through the pass-through.
