IMHO – Unless you can do all of the work yourself, I’d guess that you’ll spend much more than the car will be worth on any sort of restoration. The part$ and material$ alone will add up.
From a sentimental standpoint, it would be great to have the car all done… but be prepared – up front -for the realities.
A non-driving Alpine should be pretty low end, a few hundred $$ would sound right to me.

Good luck with whatever you decide.
