I don't think labelling Mk4 as US origin is useful for reasons already stated (even if US were involved in its design) and because it looks as if European engines used. Probably just a blanket Origin EU covers it better, without having to crawl around dissecting the precise detail. 2013+ Transit went on sale in Europe 2 years before US sales according to wiki, so origin EU seems to sit better here as well. Although we can probably leave the 2015+ US-made examples for US and CDN as origin US
