The 1912 Rolls Royce Silver Ghost specially ordered by the Nizam as a Ceremonial carriage has to be one of the most precious Rolls Royces in the world. It is a one of a kind special order car built by Barker on a London Edinburgh ghost chassis and most of the trim items are in silver. Further the car has barely ever been driven with only 356 miles on the odo.
The car was modified in 1936 in preparation for the historic Silver Jubilee celebrations and perhaps the modifications are as much a part of history as the event itself.
The car is a RR which meant exquisite standards of contruction for the times, one of a kind special order car, 1912 vintage and with low mileage. My personal view is this is the most precious car in India.
