The problem I have guys is that there kubelwagen is somewhere on the map (not in visual range) and I have to order the car to come back. I don't know how to select the car on the map (M key) and bring it back.

UPDATE, I was able to bring the car back by first pressing "space" key and then click (clicking the scroll wheel) on the destination spot. The next mission has started and I have to say the tutorials are a complete mess, I gave up on this game until it gets more polished and the tutorials get cleaned up.
