What I've seen so far from Chinese car makers (BYD and MG, to be precise) is, to put it bluntly, the bare minimum. Build quality so-so, design is… unconventional and software is just bad. It drives, but only just.
Maybe the more recent models, like the Xiaomi thing, are better. But at the moment, Tesla is at least on par, if not better. The brand being tainted is very relevant though.
