I haven't found any overland focused and in english, if you find some please share. There are many enthusiasts in Germany, but all the travel is out side of Germany. Not much to overland from what I have seen. What kind of over-lander are you interested in? I recently bought a G 300GE from AutoScout24.
Depending on year a decent G, from my research is around ~$20k US. I didn't really look for Land Cruiser - Wasn't what I was looking for. Where are you at?
