Hello

I am in the process of buying my first Porsche. I have narrowed my selection down to 2, a 1990 964 C2 with 65k miles and a 1993 964 C4 with 75k miles. Seller is asking $51,000 for the C2 and $46,500 for the C4. I am having an leak down test run on both cars this week, as well has being fully checked for rust, any other tests or checks recommended before buying?

Can anyone let me know of any issues they have had with either of these types of 964s in the past? Also any other general information about either of these cars would be greatly appreciated.

Thanks.

B
