Building passenger cars and trucks are the restaurant businesses of manufacturing. It's tough to make money at it.
Margins are narrow in the best of times. Overhead cost is insane and consumers are fickled. Complying with government regulations cost a fortune, which is why all cars and SUVs are all starting to look identical. It's an expensive proposition to develop and bring a new design to the market due to the government. On top of all this, we're probably within 20 years of electric vehicles starting to take over.
EVs are simple compared to ICE vehicles, a lot less moving parts wearing out. So we're looking at a huge shift in the market over the next few decades. With EVs becoming more popular maybe we'll go back to boutique carriage companies like in the old days when companies like Fisher focused on building bodies and interiors. ....who knows.
Then you have demographics shifting more and more to congested urban centers, where fewer people will go to the trouble and expense of owning personal car, SUV, or truck.
Something to consider is the fact that every American car company has gone bankrupt except for Ford and Tesla, and they still took some .gov money. It's not a business or stock I'd want to own.
