Car Model and destination market should be one to many or many to many association relationship?

One to many reason:
One car can only be sold in one destination market. One destination market can sell multiple cars.
Many to many reason:
One model of car can be sold in mutipal destination market. One destination market can sell multiple cars.

When we dram the association relationship, we need consider them as one type or one object?
