Jay,
Could not disagree more...the 87-89 cars are nice but look clunky compared to a 964. Sorry, the bumpers on the 80's cars hold zero appeal to me.
I've owned a wide spectrum of Porsches and looked at 993's when I was looking to upgrade. They did nothing for me. The 964 did.
It is all about individual taste.
There are also no "facts" when establishing future value...
As always, YMMV
