Where to find CMPs?

[Marauder_Pilot]

I've been on the lookout for a CMP truck to restore (Well, more realistically, resto-mod), but, unfortunately, they're damn hard to find, in any condition!

I've checked eBay, Kijiji and a handful of MV websites looking for them, and the few that do come up are always long gone by the time I see them.

I'm new to the MV community, so are there any other places I should be looking? (Besides scouring Canada's barns personally?)
