Help Needed In Finding A 964

Hi,
I'm looking for a 964 series c2 to make into a track car.:flash:
I have been searching high and low, only to find cars in pristine condition for too much money (for me) or total junkers:mad:
I'm trying to find one that has high miles and not very clean, but it has to be very sound.
If anybody comes across something like this, help would be much appreciated.

A fully prepped track car could be even better:licker:

Thanks!!!!
