I'll play along.
One detail I noticed on my '00 is the guages. The curved arcs that seperate the analog part from the digital part, all come together in nice curves, from one guage to the next.. sweeping along if you will. Kind of like a sideways number 8. I don't think the later cars do this because of additional space needed for more "digital" readouts.
Also, I love the curve of the rear fenderline. I prefer the same rear 3/4 view of a 1969-1989 911 more, but the Boxster is growing on me
