Chinese cars are literally a copy paste.
Except they are not, even the ones that are deliberately designed to look as much like existing models from non-Chinese manufactures are far from copy/paste under the skin and then we have the (currently small) growing number of Chinese cars that are not even remotely copy/paste.
Have you ever taken a look at the number and nature of safety recalls from all manufacturers? Parts that are legal in certain markets do get into the wrong markets, these are issues that to a degree have (and will continue to) affected every car manufacturer on Earth.
The second example you have given has no bearing at all on the quality of Chinese manufactured goods, yet you seem to want to take selective items and then use them to condemn the production quality of totally unrelated items and/or all Chinese manufactured goods.
Not only is it a strawman argument, but I would hazard a guess that the bulk of the electronic goods you own are Chinese manufactured.
Before condeming the ability of the Chinese to manufacture cars you should actually be aware of the level and scale of production that goes on in the country, one example of which is:
http://en.wikipedia.org/wiki/Volkswagen_Group_China
One of those factories is half owned by SAIC, which means an major up-skilling of automotive staff has already been going on for years in China.
That the Chinese copy existing non-Chinese products in terms of appearance (and it is mainly just that - appearance) is not exactly a new thing and is not an indication of a 'problem' with the way in which the Chinese motor industry is developing, its an issue with Chinese law and how it deals with IP (which is very, very different to the rest of the world).
That product destined for the domestic market are heavy clones of non-Chinese products is not exactly surprising to anyone with an understanding of the market and its laws. It gives you a product with a look that will sell and is entirely legal (in China). Now as the Chinese auto manufacturers start to expand beyond the domestic market that will also start to change as they know they will struggle to sell cloned (appearance) product outside of the home market.
However to dismiss China as a growing player in the automotive world is a very naive thing to do, I can assure you that no one within the motor industry is doing that, quite the opposite.
