Interesting, Bryan. I would have thought that nobody would call an S2 as a 1973 model since the car had changed so much in '72. That was a full year after the TCs started. I understand about titling a car in the year it was purchased. Mine was built in June '73 but it was sold to me as a '74 in 1975. But then there was little difference between a '73 and a '74 or '74 1/2 which had a few add-ons.
