Isn't it cool that our list needs to include the ISS?

My addition: Murray Fowler and/or BluMax - a retired naval officer, insurance man, venture capitalist, and one of the most well known and loved of all the e9 owners. By the time of his death in Costa Mesa, CA in 2013, Murray had put 420,000 miles on his 1970 2800 (BluMax), inspired scores of coupe owners (including me) and made a massive and lasting contribution to the e9coupe.com community.
