BYD is relying on resellers in these areas as well as dealing with import and value added taxes. The resellers will of course want a cut to cover their import fees as well as profit. Depending on how BYD negotiated their contract they may or may not have put a cap on end customer price. Now with the inflated pricing, BYD as a new Chinese brand will have to compete against not only established brands, but at a price point where they aren't that far off from the established player pricing. There's already been complaints on their pricing in Europe being too high.
My question to you, is why are you so defensive about it.
My point is that you don't know why they are doing it and it's best that you don't act like you do.
BYD will lower pricing when they are ready to do so. At this point, they are still building up their export network and they can only export so much given the transport capacity they have and the number of dealers they have.
It's also very important to consider that BYD will lower price once it starts operating local plant. That significantly reduces transportation issue, tariffs and the rest. We've seen that recently they were able to do so in Thailand.
Other things to consider is that there are significant upgrades coming to Seal, Sea Lion and what not. There is no reason to start price war in European countries when the product itself is still undergoing significant changes. You don't want to sell too many of them and then develop a bad reputation. As such, consider the current sales to be learning about European market. Things don't need to be rushed.
