Yep... we build one, called BA-64, almost 70 years ago, back in 1942...

Here is the proof:

- limited edition:
1942 - 2.486
1943 - 1.800
1944 - 3.000
1945 - 868
Total - 9.910 ever made

- AWD system

- initially designed by foreign firm (Eisenwerken Weserhütte)

- tons of modifications, each BA-64 was pretty much unique:
* different armor upgrades (skidplates??)
* machine gun upgrades (incl. the massive heavy-caliber DShKM 12.7 heavy machine gun, for those who know )
* wheels and tires upgrades (including metal railroad wheels and caterpillar belts)
* capacity upgrades to convert to armored infantry carrier (similar to 4-door VX)

- still doubtful?? LOOK AT THE PICTURES!!!!!
