I picked up a Sterilite 'Underbed box' from Wally World today. It's 39.5x20.25x7 inches and fits in the cargo area just right. I held my breath til I put it in, since I couldn't remember the dimensions when I spotted the thing. But, I figured, it's Wally World, if it doesn't fit I would take it back.
It almost fills the cargo area, very nice fit. Doesn't need the wheels though. And, the lid meets some resistance when attempting to open it in place in the Cabrio. That might not be a concern in the Coupe since there is more room there.
I think I'll likely use it without the cover. It serves the purpose of keeping stuff from rolling under the seats ... at a bargain price.
