I just inherited a 1959 PV444 from my grandfather. What to do next?

I recently inherited a 1959 PV444 from my grandfather and I'm excited to restore it to its former glory. The car is in decent shape considering its age, but it needs some TLC before hitting the road again. I've started researching what parts are still available for these old models, but I'd love some advice on where to start with a project like this - thanks!
