Both Japan and Korea had similar reputations and over came them quickly. Western consumers have noticed the pattern and will be much quicker to trust Chinese cars than they were to trust Japanese and Korean ones, assuming rightly or wrongly that the pattern applies.
It helps that the initial product quality of Chinese cars from the big makers is better than American cars. Perhaps their long term quality is worse, but that's unknowable. People will judge by reports of the quality in the first year of ownership.
Chinese cars will also be helped by the use of purchased Western brands like MG and Volvo.
Compared to the same vehicle manufactured in the US, the general finishing and fitment is superior (based on people with access to vehicles made in both countries).
I have no complaints, was in better shape on delivery day than my previous Audi, which had been through “detailing” (a.k.a swirled to hell by an unskilled operator).
