I purchased 2 of the first aid kits from the dealer for about $35 each. I installed one under each of the front seats, stocking the passenger seat kit with first aid materials (the kit box isn't stocked) and the driver's seat kit with oddment stuff. Also, because the driver's seat kit isn't used for first aid materials I scraped off the green cross on the front of it (used my finger nail, came off EASILY).
