Just because the Capitalists that own the company, reside elsewhere right now, doesn't mean the end. Some day Tata will grow tired of owning Jaguar, etc. and some New Wealth UK guy will take it back. Bear in mind that BMW is not doing so well right now and they may have to disgorge themselves of their British origin marques as well. Rolls Royce of course, plus "Mini" is sort of derived of Austin and Morris and Riley. So long as there are UK men and women who know how to design and engineer and assemble iconic cars, and vehicles are being assembled there, you have the pieces you need. Just, don't take too long at it.
