lol no doubt about its benefits to handling and centre of gravity. but thus far most japanese cars have kept to a certain size restriction to make owning one in japan easier for the consumer.
just keep in mind a large chunk of affluent people live in the cities in japan. parking space is limited, heavily regulated, and expensive, and the R35 isn't the be all to end all supercar, its just a $80,000 car. people park more expensive mercs on the street. crime's not quite the same there as it is here.
