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?
Getting the chassis would be hard, usually that’s not a “part”. But you could by a second hand/wrecked car and refurbish it with parts. It will be expensive and not easy, but possible.
Possible is good, and the used market has some candidates…
You can buy a kit car, but those are mostly targeted at people who want to build an affordable sports car.
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?
No, absolutely not. Even if you could buy the 30-50,000 parts individually, the markup alone would absolutely kill the feasibility, much less the ability to weld the frame components together, assemble the literal miles of wiring, or program the computers.
That is a good point.
There are some cars that are sold this way, apparently. They built one at the start of an “expedition” episode on the Amazon Prime version of Top Gear. (Is the show called The Grand Tour? Something like that.)
