Looks like a solid car to restore assuming there is a floor still in place once the carpets are removed! You didn’t show any engine photos but if it runs and the mileage is correct there is lots of life left in it. It may even have an overdrive which is a plus. Is OD stamped on the chassis plate? Early big fin Alpines that run and drive are getting pretty rare so I hope you can restore this one. As far as a price, I paid nearly $1000 for a S2 that had a body in far worse condition than this one. You may be able to cut out the small window and restore the top. If not, they are still available for low prices compared to the later hardtops. I think it is great that you want to keep the car in the family. Keep us posted! Eric
