Gargoyle Cabin Treasure Escape

From a good friend, you know that in the same forest, in the territory of the military base, there is a dump of vintage cars. In one of the cars are hidden treasures. Just like that to get to this area will not work and you decide to visit the official tour on this base. You quietly moved away from their group and went to look for these treasures. You need to find them quickly and return to other tourists, because if you do not find, it will cause suspicion.
