Back in the early 80s I had a discussion with a gentleman who owns a Jaguar dealership here. He told me that when someone wants a new Jaguar, he has a "special talk" with them. The prospective customer needs to know that these cars require "frequent attention" to keep them running well. They are not a good choice for reliable, affordable, basic transportation, he said. But they can make a wonderful "social statement."
IMO, Jaguar's similarity with Leica ends with the social statement. And I wonder about that. Most folks do not even recognize an M3 when they see it. But they probably would recognize a Jaguar.
I have never owned any other mechanical device which I felt was equal to the Leica M3 in terms of concept, fit, finish, ease of use, maintained value, freedom from trouble, and durability. Nikons F and F2 are close.
But I have owned three European cars. One Triumph and two Mercedes. My uncle who is a life long mechanic says of them "When there ain't no oil
under a European car, there ain't no oil
in the European car." In my three samples, he was exactly correct.
