i think the key to this is building (and selling at a price that actually makes the company money) passenger cars. family cars. toyota and honda build their success in this country one customer at a time through the camry/corolla and the accord/civic. they grew it from nothing to where they are now. the big 2.5 have seemingly surrendered this market for far too long, and now are paying the price. this problem did not occur overnight, and it won't be solved overnight, either. it is going to take years of discipline and some long range planning, which with their focus on the very short term quarterly earnings reports, might not even be possible. honda and toyota had a longer term vision.
if that doesn't sound like something to their liking, then here's a guaranteed strategy for success for them. just hire 20,000 more salesmen, and call it "project surge". hey, that's just gotta work, right?
