How much value difference between 1991 vs 1992 964 C2?
 

I could be wrong, but seems I read somewhere that the 1992 964's get a bump in value over 1991's, and not just for a year newer. Am I remembering wrong? If my memory is correct, what changed? How much of a bump? Are there other years of the 964 that had an improvement warranting big bump in value?

Thanks

The '89-91 cars had some cylinder-to-case sealing failures that were fixed with the '92 model.

It has been years since i had a 964 but if my memory serves me there was changes from the fractory in late june 92. I believe it was the ventilation for the distributor that was fitted.

Many of the earlier cars have had this mod fitted in the after market, though.

I believe thatvthe info is here.....somewhere.

About the value of 91 vs 92.....second to none - assuming the cars are in the same condition.

93 and 94 are another breed. Very very limited production and rare colors. Signal Grün, Speed Yellow, Maritim Blau etc. worth 50-100 % more than similar cars in conventional colors.
