They are nice to drive, handle great, and are even decent to work on, if you have a lift to get underneath, since that’s where most of the service items are accessed.
The problem is that they had an un-oiled bearing supporting an intermediate counter shaft that can(will) fail and often kills the motor (also a problem on the IMS bearing of similar aged 911s). If it’s had the bearing replaced, and especially if it’s been upgraded with a solution to oil it, it’s usually a great deal too.
