Then I ll tell you which are the best vehicles: Steamship and Spacecraft

The Spacecraft is even better than Mighty Plane and Jalor. Because his fuel is Diesel Oil, like the Jalor. And it can fly like Mighty Plane and also has about 3-4 times more fuel space than Jalor. It can also carry 2 persons, so it is kinda a combination of Mighty Plane and Jalor. Only to manufacture the spacecraft is kinda tired, but sure worthy, even better than build the jalor and the plane.

The Steamship's fuel is Coal Block, also easy to make. You only need 4 Tars and 8 Coals. I m sure you will get a luck from recycle coconut oils to get tars. If it failed, then it will be just crude oils for diesel oil. And Coals are easily compounded from coal ores. The advantages of Steamship are: to travel much longer (about 4x) than the jalor and to able carry 4 persons, a full team.

If you have both in your garage, then you will never need other vehicles and also you will be the proudest player. Because they are the most useful vehicles.
