I have made use of the first aid kit a few times if only due to those times when I'm out someplace and get a minor cut I *know* where to get a band-aid. The kit is pretty minimal but since the sack has lots of extra room I suggest, along with the others, to stuff it with additional supplies. But if you can get a better first aid kit that fits (in the holder on the rear door), buy it.

PS - this is the first vehicle I've owned that has a first aid kit. I now think such a kit is absolutely A MUST.
