The more I look at the 964 cab market, the more I realize that they don't move that fast. I see many that have been up for sale for 2+ months and that's not something you see a lot with 3.2. Also, they seem to be somewhat low mileage in general (most, if not all, below 100k miles which never happens with 3.2).
It tells me I should not be paying $40k for the 93 C2 that I am taking to PPI today. Will report back
