If you like learning how things work, like to learn lots of things and want a good subject to motivate you, restore an older car to perfect working order. You will be investigating mechanics, electronics, chemistry, metal working, even upholstery. Hell, I got into 3D printing too since some of the older plastic parts simply aren’t made anymore.
And at the end of it, you get a sweet perfect vintage car to show for all your learning.
