Geegad, man,that Staff car looks good, really good...
Maybe you had tought about it before, but for that kind of "brass" staff car it would be really a class touch to add the comander´s flag or so, just like this (the same car that yours! ):
Some days ago I just saw a Waffen SS flag in a staff car (it wasn´t your model, just a VW or so) that loked sharp, it was a "Totenkopf" in one side, and in the other one (in the other side of the vehicle) there were painted the SS runes...
