I had spoken with Claus a couple of times in the past, but was not aware he passed away. The picture you just posted of the touring is one of my favorites. Taken at the Amsterdam Auto Show in 1971, it shows a tii touring with the rare factory "sport paket" including black Recarro interior with cream piping, US turn signals, Hella fog lamps, sport steering wheel (same as the 1600ti), and alloys. I am quite fortunate to have a touring that has this sport package. Another owner I am aware of lives in Switzerland and sometimes posts on this site. His original inka tii touring has been in his family since new. Would be great to catch up again in person.
