Thanks for the info guys. Regarding my fathers 250SL, after 40 years of being told that it would be left to me, he changed his mind at the very end and decided that it would be sold as part of his estate when he was gone.
I was unhappy about this, and I told him so in his final days. We did not have a single issue dividing us... this was not a personal affront on his part.
Dad would have made a great German. He was coldly logical, and his decisions were always based on logic rather than feelings or emotions. The 250SL took its last ride with him about 4 months before he passed. It was of course driven by someone else (not me), and the driver did not pay any attention to the temperature gauge.
It overheated on Rockville Pike. Dad told me that most likely that the head had warped. This was the condition that the car was sold in.
I do not know who bought it.
Dad had Retinitis Pigmentosa... a condition that caused him to become mostly blind. I have it too, and I am legally blind, unable to regularly drive although I do get out there with the help of a co-pilot occasionally.
I enjoy life, I enjoy tinkering with my 5 collector cars, and I am looking forward to a day sometime in this decade when medical science gets me fixed so I can be "a real boy" once again...
