I think as the default choice for someone who sees their car as a domestic appliance the Koreans are already there, just look at the scrappage scheme numbers.
Ford and Vauxhall are in a bit of a limbo I think, not able to challenge VW or the premium brands for desirability, more expensive than the Koreans and with Renauly and Peugeot starting to build desirable cars again, and Dacia (and even MG) coming in at the budget end of the market they are getting squeezed all over. The saving grace for Ford is that they make nice cars which are good to drive and that's enough to sway some buyers, and I can't say the same about Vauxhall right now...
