Restoring the car

I’m still new here, so please be nice to me I’m a total beginner on the topic “Auto & Co” and have no precautions (I’m not pre-loaded *g*).My question is now: I’d like to buy an older car (that’s what in the currency 2CV, mini or beetle) and at best also restore or put my own hand if there is something to repair. However, I can’t estimate at all what would come up to me, therefore w should I ask here if I could do something like this as a layman at all… Is it possible for me as a non-craftman to restore and/or maintain a car at least partially with the right guidance and the right tool? Or do you have to bring some know-how and dexterity with you? I’m sorry if the question is perhaps a little too general, or not quite clear, but I didn’t know who else to turn to. would be very happy about your answers! Greetings from Switzerland, Marcel
