+1 for Beetle. Very easy to work on. Engine comes out with a 17mm spanner, a trolley jack and a skateboard (ok maybe some swearing as well!)
Pick your project well, whatever you go for. Working with rot really isn’t the fun bit, so the less you have the better. Take someone who knows that particular sort of car when you go to view a potential project, and DON’T let your heart rule your head
Restos=moneypits if you’re not careful!
Good luck
