Answers: The original Tiptronic (G64) be first offered in 1989 - though just on the 964 Carrera 4. In 1990 it was offered on adjectives new Carrera models, and would construct it's way across the rest of the model row soon thereafter.
The earlier Sportomatic be offered on some Porsche models from 1968 until 1979 (though it is generally much rarer than the Tiptronic). The 924/944/928 models be all offered beside Automatic tranmissions while they were available.
Think it be 1990 and it was within a lovely yellow.
