LOL I was mostly giving you a hard time. I guess its hard to explain but i know what your going threw and so does alot of other folks. Once you demand perfection from one part of a project, you tend to carry that over to all other parts of it. Yours i believe started with the interior. Then the good old might as well syndrome takes over.
You are just doing what thousands of other car guys do. Look at all these restored/resto-mod cars out there that are full on jaw dropping perfection. They all have the same thought process and mentality as you do right now. So its not exactly crazy, its just more like a "fun" obsession.
I have this theory that its a psychological thing where its a way for your subconscious to gain "control" of something and a having "perfect" element in your life when, again, subconsciously, your brain finds itself lacking in those areas. I think its mostly brought on by stress at work or perhaps a stressful time at home or with family. Not saying that any of that applies to you, just saying that is my theory.
