They're an interesting concept... Something Emma and I have been considering since fitting the exBox.
Observed that "Easy" access involves spinning off a wing nut, and loosening another one. Likely to result in lost Wing nuts!
In that time I can pop the seat, slide the panel - and not a cut be made in the vehicle...
I cogitated when was the last time I actually used my Jump leads - it was on my Sons first car - that's 2010.
Our First Aid Kit and Fire Extinguisher are reach and grab items - not in a box which can potentially be crushed shut in an impact..
I don't think I personally would cut the side out of the seat box for such occasions..
