I've been doing an exhaustive search on which cooler has a perfect fit on the M3 trunk's hidden compartment. So far the best contender is a freezer bag called "AO Canvas" which still falls short for being 8.5" in height when the compartment is at least 10" tall. Once I'm done I'll share the spreadsheet with everyone.
Though during my search I came across all the electronic coolers, and found a couple that not only keeps cool but have a compressor which can actually keep freezing temperatures. In particular, one actually fits in the hidden compartment. Though the downside is that the chest can only hold 15 liters, it still fall under the category of fitting in the trunk's hidden compartment that I can always have it with me.
It just so happens that there is a lightning deal on the chest for 20% off, so I figured I'd post here before I finished my research.
(note that the deal expires at 3PM, July 17)
Alpicool CL15 Portable Freezer
I'll post a review after playing around with it.
