Agreed! Most cars, esp BMWs have a lift up section in the trunk for extra storage. Even the 330e with the pack in the trunk has a little spot to stash stuff.
I'd even pay them if they itemized it on the window sticker. Would have been great to intro it during the LCI refresh. Lost opportunity. Bummer.
in lieu of the shortcoming, I'm eager to try and craft an extension in the empty spot, for a beefy subwoofer.
