That is thing that designs a car very special, so incredible, so wanted? Is it the glossy and streamlined shape, thought up for bowel-loosening prettiness and maximum speed efficiency? Is it the inside of the car, snug, elegant and useful, bespoke made from the best elements open? Is it the machine yourself, a marvel of manufacturing, running smoothly and able to go from nothing to sixty in a case of seconds? Or is it the sign of the car's makers, a name which conjures senses of esteem and admiration?
