In upgrade I meant an upgrade to the already owned vehicle, and not as an upgraded separate vehicle.
I do consider the insurgent pick up a replacement to the insurgent, but like I said, the pick up custom is (in my opinion of course) an upgrade to the pick up.
Anyway, we are arguing over the definition of “replacement” in this subject which it isn’t even used in the actual game. I simply meant what vehicles you gonna use it instead of them, and I just didnt like how 60% of the replies were about the mk2 being a replacement to itself, un-upgraded. And yes, I do consider, and it’s just at least my own personal individual definition to anything that you do in the MOC/vehicle workshop/ammu-nation/hangar/whatever else that improve the performance of the vehicle/gun an upgrade.
Sigh....
