The interesting thread here is that Jaguar is not, in fact, an American invention. After ruining the cachet of their own Lincoln brand, Ford's corner-cutting did the same to a British marque. For example, it is nearly impossible to make a V-6 sound as good or rev as smoothly as Jaguar's traditional inline sixes, and Ford definitely didn't go to the trouble.
So, here it is Ford losing its corporate shirt trying to buy overseas cachet and reform it in their own image. What's bad for us is bad for them, too. Corporate homogenization is very akin to a city man's affection for the dog. To quote E.D. Worley, "Great benefits are anticipated at the outset. Few concretely appear."
The Indians could turn it into a good investment, provided they remember that "it's the product, stupid." Only the product can maintain the cachet in the end. I personally think that India making a go of the British cat would be a fascinating bit of reverse colonialism. It would certainly be a hard lesson for the ingrown fatcats of the more established corporation!
