I`d wait until I have the bird to work on, that will probably help decide which tools you need, like depending on what the car you buy is most in need of... a good flip up carrying kit with all sockets , some pliers, a hammer (metric!) a few screwdrivers may get you started though...a kit that you later can keep in the trunk on cruises...
a small jack, jack stands and a crawler might be good for a start too....
an extendable magnet for when you drop nuts ,bolts etc in bad spots, and a small extendable mirror...
