Since there seems to be a growing car show out here, I thought I would add my own entry. My favorite cachemobile was a Hummer H3. It could do some amazing things off-road, as deomonstrated at the 4x4 caching event out at Interlake back in 2012.
This location seemed appropriate for the cache ... an old ATV trail and a creek crossing ... just what the H3 liked. You are looking for a preform container. And my H3.
