I think that's pretty neat looking. I like to "one off" theses cars and modify them and still keep a factory Porsche look. It's why I like my Aerokit cars with a hardtop. It gives the Boxster a unique look.
My ultimate Boxster build would be a 2004 S with a Zeintop, then swap fenders, front bumper cover, headlights and associated parts with a 996.2 GT3 front.
I've seen plenty of Z-tops that I like the look of, and I've seen several 986 cars with second generation 996 front ends. I have the parts list too to make the swap. It's not overly hard to do.
Then top it off with a built Jake Raby engine.
Would it be expensive to do? Relatively so compared to a stock 986. Would it be easier to buy a Cayman or a 996.2? Yes. But that's not the fun part. The fun part would be planning and building the project and having a totally unique Boxster with a factory look.
And oh yeah, make it Zanzibar Red with a black interior with GT3 seats.
Imagine the comments and looks of confusion from the old air cooled 911 purists as they tried to figure it out.
