    Is this wrong? Worlds most expensive car - £20 million!

    I dont know what others think, but I cannot help but feel that there is something wrong with a world where someone can afford to pay £20 million for a car. It is certainly a work of art, and certainly puts my humble Seraph to shame, but can any car be worth that much money? I do believe that...
