I love interesting car history stories like this. My current daily driver belonged to a former mayor of the city of Woodstock. He bought it new and optioned it exactly how he wanted it. Thought that was kinda neat.
The last 10 or so years of my E30 are documented pretty well online and I have all the original warranty service books to fill in the earlier gaps.
Anyway, hope you can get rolling sooner than 10 days! I'm hoping to drive mine for the first time tomorrow.
