Note that I think the BYD quote of 29 or 30k euros is including VAT [1] which is 21% in the Netherlands. On the other hand the quote given above as the starting price in the US for the Mach-E not include sales tax. In the Netherlands (trying to compare apples to apples), the Mach-E is being sold for €75200 [2]. Significant price gap in that market.
