I lived in China from 2012 to 2014 and yes, that video is all very true, the difference is it the car was a status symbol to indicate you were a potential partner who could support them. The house was an even bigger status symbol in that equation. But as a status symbol the only thing that really counted was the cost i.e. do you earn enough to support me? They were not chosen as penis extension, and were seldom customised. Owners generally had no idea what was under the bonnet or what transmission it had etc.
The normal process to buy was to go to dealer and pick one that fit your budget. The sales staff where very confused when I asked to test drive the model I was interest in, apparent Chinese buyers picked one they liked the look of and paid for it, they never bother to find out what it was like to drive first. My co-workers where confused about why I brought a cheap and tiny BYD F0 with 1L 3 cylinder engine when I could afford a more expensive car. I brought it as it was fun little car to drive and I was not seeking a partner. They were also confused why keep and still used my motorcycle when the weather was good. It was faster and fun, but from their POV it was lower status so they would no longer use one once they had a car. A different way of thinking about vehicles.
This is why BEVs are popular, they are simpler to own and use and the Chinese are not hung up on the sound of the engine, rolling coal or having the carrying capacity of a truck. I realise there is a subtle difference between ego and status, but in the case of cars in some countries it makes a big difference in the buying criteria.
