IMHO, it depends on the particular volume Ford might expect to sell. Gallardo-type sales, or full-bore unobtainium? One is about 3,500 vehicles per year, the other is 300.
The point is, at 3,500 per year, I can see MM working with Ford to develop Ford-sited composites assembly chops, but at 300 a year, IMHO, that would stay within the MM operation. Either way, skills and machinery like those used to fabricate the composite weave "A" pillars in the Lexus LFA would be a great addition to Ford engineering know-how, IMHO.
