The problem was that you used return even if the player wasn't near to the vehicle, it made the loop stop in the first loop. I moved that return outside the loop, so it says that message AFTER it has gone through the whole loop.

Also I moved floats x, y and z outside the loop, so it won't create them again and again. Saves time.
