+1 on the heavy understeer characteristics of 964 AWD. Although you asked about the AWD, the biggest concern I have with these cars is the problems many of them have with head to cylinder sealing.

Cars built from 89' through mid 91' had a had seal structure that didn't use gaskets, many of these seals leaked and were either repaired by Porsche, Previous owners updated or they are still stock. This is very expensive to update to later solution involving removal and machining (plus all the while we're in lets do... costs).

Estimates very from "all" of these cars eventually leak to "many" do but you can be in for a very large shock and bill. I would not consider an early 964 without proof this work has been done or allow a major discount even if it's dry. Another mid $4 figure+ reason for a good PPI.
