Rolls-Royce has been one of the world's top luxury car companies since its beginning in 1904, and in 1906 they released the 40/50hp Silver Ghost model. The car soon became one of the finest luxury automobiles in the world, recognized by its ruggedness, quality, power, and reliability. Now, some lucky anonymous buyer is a proud owner of the model, having outbid everyone else at a record-breaking auction put on by Bonhams on June 29, 2012. The classic vehicle sold for $7.1 million, making it the most expensive Rolls-Royce ever sold at an auction.
