option code 718 indicates a car that didnt sell during the year it was manufactured, and was "re - VIN'd" by the factory for sale as the next model year. This was apparently the case for many of the 968s.
In fact, my indie mechanic's 'conspiracy theory' (chuckle) based on info he heard and cars he saw during a tour of the factory (mid 90s?), is that they were all made very early in the model run, and then badged for sale year by year.
In any case, check the driver door badge for the date of manufacture. For your case, all 95s were made in 94 (or earlier?). The 718 code meant the car was sold as a 95 model year.
Im sure others will chime in with additional details, or perhaps corrections.
