Sacred 2:The Flintstones
While scouting South Jungle Island you encounter a cave. Inside the cave you find replicas of many different vehicles, among them one just happens to be The Flintstones car.
This vehicle may also be found located on a tale in a cabin on the road to Wargfels just east of the Grunwald Horse Trader.
Note: This vehicle is environment friendly as it is powered by the feet of the driver and/or any capable passenger.
