It'll be hard to tell w/o a bit more information as there are quite a few Lapis Blue Boxsters in the Bay Area. the full natural leather may provide some additional insight though. Any service records indicating what dealership was involved that may have come with the car?
This Boxster S is pretty loaded option wise. It has PSM, Navigation, Sport Design Wheels, and the Roll bar painted same as the body. Probably like looking for a needle in a haystack. It was originally sold at Carlsen. Just curious.
