As a little exercise for myself, I've decided to write a little
command-line c program that will be able to compile statistics for the
list.

I was thinking that 5(+1) factors should be sorted.
Year of van
Color of van
Type of van
Country of owner
City of owner
(not visible in the statistics, but important if one person owns two vans,
 and important for eliminating duplication; email of owner)

Please let me know what else y'all think would be cool.

Thanks,
Sudhir
