The company
http://www.kamitiro.de makes a 4wd conversion kit for Marder and such...
List price € 1499,- without body, wheels, engine, exhaust and rear dif(guess from looking at the parts list)
http://www.wws-racing.de had announced a WWS Fox Pro 4wd version with a kardan drive, but I have last week received information, that due to lack of interest on the German Market, they do not plan to make any more 4wd versions.
Do they know that USA is still around?
