Thank you all for your interest and kind offers; have never before been offered desirable sports cars as swaps! Discretion dictates that I give no details of the sale. But what I will say is that both the seller and buyer are delighted, and I am especially pleased to be able to report that the 101 is staying "in the family", so to speak; it is not going to some opportunistic dealer, but to a real enthusiast. And so gratifying that he had read this blog from start to finish and so appreciated what I have put into the project.
Saying goodbye to 3591 NG will be a wrench after all these years, but it will be good knowing that someone is going to finish her properly.
