The same way as one would buy/ pay 1 million for indus 98 which is ready available in market for around 700K (TOP NOTCH)
still anyone buying this bumper would be benefited than ending/ bearing loss in investing 1 million over that particular disgusting rear seat one.....
i still believe someone would buy it in curiousity to know how could that be done... OH gosh! worse than a car driven on rent.....yuckh one not feeling well could easily vomit.
