Bagging, tagging, and photographing EVERYTHING is a must in this situation. Any one of us would be thrilled to have a chance to lend a hand on this. Please keep us updated as you can.
Also, I would strongly suggest that you get insurance on this car, if you have not already done so. I expect that you turned an awful lot of heads while transporting it down to your home, word travels fast as you no doubt are aware given your profession.
Cars like that draw a tremendous amount of attention, not all of it is good.
