I like a certain unremarkable car from the recent past. As they are repairable currently, can one just buy all of the parts new and put it together?
Are there any parts that aren’t sold new?
Have you done this?
Are there any tools to help one get all of the parts?
Any communities?
I love these kinds of questions! Car culture is so extremely broad, you need to narrow it down a lot to get a fitting answer. What car are you talking about?
