Actually until recently I would have made a significant profit if I sold it (especially if I put in another 1k or so to clean up the old paint). Now you're probably right, no one's buying things like this. I like how a friend of mine put it recently about selling a car you have so much time and emotion invested in, for "fair market value": I'd rather just set it on fire.
By the way, post any updated pics of the 6! Did you start on the schematic paint job?
