The 928S was my dream car for so long it's embarrassing (eg. see Tom Cruise's "Porsche: There is no substitute" in Risky Business). A few years ago I got very close to buying a very nice mid-1980s model, but was told (by the engineer we asked to check it out) that Porsche were about to stop making the parts. I don't know for sure whether that was true, but it was enough to put me off the car.
I bought a Nissan 350z Roadster instead. Two years' later, I still think it was the better move. Those Nissan engineers may be certifiably insane, but they make a *nice* car.
The wife got a 2000-model Boxster S -- could be another option for you.
Cheers,
