Good afternoon Oldcarguy. I just re-purchased a 550 (#1363) this week and wanted to see if there is anyone documenting the 550's in the U.S. that are still titled and operating. Looks like you have been doing something in this area? Oh, purchased my first 550 (#63) in 2011. It had 365 miles and was showroom quality. Silly me, I sold it in 2014. I did track it down to a gentleman in Iowa. He was not interested in selling it to me. I believe he said I could buy it when he is dead I could not wait so I found and purchased the one I have now.
