Hi, I am totally new here and about the starting issue, I believe in Latin America Sidekicks are just Sidekicks, they are called Vitaras in Europe.
The one you saw is probably imported in used condition from there to here!
As far as a turret in a Zuki... I imagine in Colombia and some of the recent wars we've had around here, someone had the idea but cannot confirm; what I've seen are pictures from Lebanon, Colombia, Nicaragua and wherever of toyota pick ups armed with anything on their beds, from a nice group of friends displaying RPG's to more or less well installed MG's, like M60s, Degtgyarev and anything in between.
And now you mentioned, I figure that's why they invented the AK-74 with collapsible stock! To fit in a Suzuki!
(but please don't ever make me talk about guns, It is against he rule of my order)
