Answer:
False
Explanation:
As per the Porter's Five force the force of supplier is described as follows:
The suppliers sets the price of goods that can be controlled by them, that depends on number of suppliers of inputs for the goods, if there are less suppliers then the price will move according to suppliers as for high demand there are low suppliers.
Further here it is provided that the price is determined by auto dealers, of a product for which consumers cannot derive the true price that means, that the suppliers can add any profit margin.
This will not make the supplier force weak in any respect.
Therefore, the statement is False.
