Soldier Force APC for Cheap
 

Not from me, but ebay. (If there's a policy against auction links, I apologize)
BCP Military Fighter Tank Truck

I've never owned that one.

That's kinda cool and looks like a 2-seater. A lot of recent "off-brand" vehicles have been scrunched on the sides so they look good in a box, but they're about half as wide as you expect, sometimes with room for only one in the cab. With the light bar on back, this is begging to be repainted in SWAT or UN colors, but I guess it'd work with just about any faction for urban pacification.

I recall that there is/was a SWAT version who knows how hard it is to find at this point.
