Having previously owned a Chinese car (Great Wall H5, bought new), I'm on the fence about buying Chinese cars. Initially it was a great car -- lots of features and they used high quality OEM parts (e.g. a Mitsubishi engine). However, I found that it didn't hold up well* and was missing some of the touches that come from engineering not coming from a car culture. As one example, the tensioner for the accessory belt was a single 14mm bolt. Technically it worked, but it was not fun. Meanwhile, even my '85 Ford Escort had a half-inch square opening in the belt bracketry that accepted a half-inch socket driver/breaker bar for setting the tension. I don't think this is uniquely a Chinese problem, as I heard similar complaints from owners of early Nissan/Toyota full-size trucks. Toyota was able to eventually improve, but Nissan had to pack it in on the Titan.
*To roughly quantify, I'd say mid-to-late 80s Ford/GM car, not 70s Ford/GM car. It never stranded me, but it did break a few times in inconvenient fashion.
I don't think Chinese cars ever came into their own until two things happened:
- A move to automate auto factory lines in Chinese auto factories. Up until about a decade ago the emphasis was still on using human labor, and quality took a hit accordingly. Robots are much more precise and consistent, the quality difference between a Chinese-made cars and the same kind of car made in Japan was huge.
- EVs. EV motors are just more reliable in general, and are easier to replace when they wear out or are defective. You don't have so many moving parts any more, and the Chinese became world leaders in battery tech.
If I ever live in China again and need to buy a car, it will definitely be an EV. Heck, I would never buy a BMW ICE (maintenance sucks) but I bought a BMW EV...
