Sounds like you been busy man. Your car is quiet awesome for sure. I'm into Euro's strictly myself but your retro aspect into modern muscle car looks kick ass. I love the hood cables. F'n mean!
The music hobby is mainly fueled by what you say, I agree. IMHO I think it's due to the fact that music is a dead and lost art for the most part. When these things happen people often cling to doing things in the name of being a musician that are not in any way ...musician. Things like, working on amps, creating or significantly modifying music gear, Comradery groups of buying/selling, collecting, testing, and the reviewing of gear. Getting a YouTube channel in the name of being a musician where one is all focused on multiple camera angles, the best broadcasting gear, their broadcast voice and broadcast overall ability. The biggest thing that will turn off a modern musician is topics about music like music education, notes and theory, making music, and links to actual music. Now, there are people that do those things, even here, but I'm not calling or pointing out names. I'm just being general.
GearSlutz is a great example of music being a dead art - if you put a group people with the same interest in a room together, they will sit and embrace in it with excitement together, share ideas, admire one another's work, etc., but when the interest dies ...especially as a result of the art dying itself, they will become bored and eventually fight, become critical of one another, jealous of one another, and may show interest in these "hinged" topics that are just a mere distant sort of association with the original interest.
My .02. Maybe even .01.
By the way, don't you hate when you're really cool and helpful to an individual then they turn around to be a complete wining jealous ass-hat? Just a thought.
