Since the alpha there has been wrecks of a silver van dotted around the map. While I can understand why so many of the other wrecks do not have a working counterpart. The van seems to make little sense especially as it could have a few of uses.
Possible variants:
Basic van with large storage space
Ambulance (CIV/FIA)
MPV(Transport truck)(CIV/FIA)
Repair truck (CIV/FIA)
Ammo truck (FIA)
Taxi

It could also use the modular system that the offroader uses and include beacons as well as other stuff.

In the end a addition of the van would fill a few gaps in the FIA support and give some more variety to the Civilians too.
