First of all welcome to the Group Alex!
If you look at it as a labor of love (meaning you would have to basically enjoy doing this type of bodywork) and are willing to not count all of the hours you will spend on it, it's certainly worth it in my opinion. If you can apply some discipline to the process, i.e. a reasonable schedule that gets the car done so you can start enjoying it 'soon enough', you will get rewarded by (1) the pleasure of driving a timeless elegant classic and (2) the knowledge that you saved one more of these time capsules for future owners (we are all just temporary holders, no matter how long we stretch out our period of ownership - our cars can outlive us!).
Besides the hours, parts and elbow grease needed, you may need some advice from time to time, and possibly some encouragement. Both can be found here in great quantities ...
Good luck on your decision; others please chime in and please let us know what you end up deciding.
