Have you looked into listing on Bring A Trailer? I sold my Dad’s 1972 Celica on BaT last year and was delighted with the discussions the auction brought. I thought I was really able to share the history of the car, and I was more than delighted with the family who bought it. For something where it is an uncommon car, that you know the history, and especially if you have receipts for the parts or work done, BaT is just a great way to sell.
