Car companies start or end production and/or sales in a location for one reason alone…profit.
In the past, there might have been some measure of hubris that led companies to enter markets because they felt doing so was prestigious or a flex of their global power, but that era is over (aside from specialist marques).
Generally speaking, if a company chooses to make cars in a location it’s because that location is somewhere that sales are high, labor is cheap, and/or there’s good connectivity to global supply chains. The other big driver historically of local manufacturing is protectionist trade policies, something that’s deeply affected auto manufacturing in places like India, Australia, and South America. When those policies are liberalized or scrapped, the operations they spawned will almost always be the first casualties in any rationalization.
