Nikon cameras are very good and have a reputation for dependability. However, the attention to detail that is given to Leicas transcends what anyone would normally expect. It has to do with the German psyche. For many years a Leica could be sent back to Leitz to be refurbished. The camera would be completely disassembled and any worn parts replaced. The body would be rechromed or repainted and the leather replaced. If necessary the lens would be repolished and the coating redone. This service applied not only to current models but all previous ones too. It involved the pride of Leitz in all their products. I am not aware of any other manufacturer that had a similar service.
