Since you haven;t gone too far with the mod's, I'd recommend returning the car to completely stock and sell the aftermarket parts piece by piece. I know that this will be a lot more effort and a PITA, but most used Boxster buyers are Porsche newbies and they think that any car with mod's will be a "project" nightmare and will stay away. Once returned to stock, you can advertise the car as completely original, which is what most buyers want to hear.
