Hi Andy,
I'd like to give a brief answer to your question about the car being a "member of the family." Before I bought my 230SL, my father-in-law had a 1960 190D "Ponton" in his garage. He bought it new, drove it through 2 tours of duty in Germany and across Canada a couple times, and then parked it in his garage around 1974. I came on the scene in 1975 and had only ever seen it myself under a pile of garage junk. So when I prevailed upon him to sell it in 2010, it was like losing a member of the family for him. The good news is that I think he realized he had to let the old heap go some time, and I didn't hear him or any of the other members of the family complain. Happy ending, I guess.
