Need some advice

Hello, this is my first post here, so sorry if I'm missing to tag something in particular.

Well, as the title says, I'm looking for advice. I recently bought my first classic car (a 1976 Ford Mustang II), and since it's my first car of this style, I'd like to ask what things I should be aware of, how I should maintain it, and that sort of thing.

Thanks in advance, and I hope you have a good morning, afternoon, or evening, depending on when you see this post.

P.S. If you have any questions, let me know and I'll try to answer with the little knowledge I have.
