Hi
You are looking at a 400+ man hour job just on rust repairs - as long as you appreciate that & can smile through the process of finding more "rust" it can be enjoyable to rebirth a car!
Paid someone to do a 300 hour rust job back in 2007 & very happy with the results - even though (after sandblasting) the car looked more suitable to strain spaghetti in an Italian restaurant!
Gook luck
