i don't know why you don't drive your old V12, but they are fun to drive. some day you might hear about the story of "old blue" there was a v12 that went every place and was even stolen. the story is in a old copy of TWOTZ. it was his only car and drove it all over creation. so how much you drive it depends on you. If you don't use it the seals dry up and leak. if you break down on the road look in the book some one might be right around the corner. cars like boats need to be used to keep them in shape. this is my experience opinion.
