Except it’s rarely the “same car”. For example a Tesla Model 3 manufactured in China has an LFP lithium-ion battery, while the US manufactured ones use an NCA lithium-ion battery. It’s by far the most expensive component of the car and LFP batteries are much cheaper.
There are often other differences too - such as optional extras being standard in one market. And warranties vary (those are not free - it costs money to fix faulty cars and they factor it into the sale price).
Sounds like what I’d like is whatever options or differences that make the car half as cheap.
I think their implication is that whenever they’re selling in China is kind of trash, and you wouldn’t think it’s a good deal if you looked closely.
