I don't think we are going to agree here
Let's say BYD doesn't get those plants. Now, the Germans/Americans are out of the China market. BYD loses 1 plant and maybe a few hundred stores in Europe. Let's say it sell those at 20% discount.
On the other side. Thousands of VW/BBA/Tesla stores in China are suddenly out of work, same with their sales staff. BYD will have its picking of store locations & sales staff that it can snap up really cheaply. Since those foreign JV partners are suddenly left with factories and no work, now there is a healthy selection of available workers with industry experience you can snap up. The land/facility of those old factories are available for really cheap. BYD can quickly snap them up and put the latest tools in them and voila.
If you have seen how quickly BYD has been able to build new factories and tool them, you would think this is not a problem at all.
There is a lot of excess EV and car production capacity in China. So there are already many car factories and dealer locations for sale.
So it would make sense for Chinese companies (BYD, Geely, SAIC, etc) to ramp up their existing factories to full capacity first.
Plus in terms of BYD's European strategy, they're working with existing dealers rather than building out their own network. So I expect the dealers are funding much of this. It makes sense from a risk perspective because the dealers take on much of the cost.
