while i understand what you are saying, i think the operative word is original vs. genuine ... two very different things. we can all put genuine parts on our car and that would probably not be original (possible, not probable). it sure looks as though the PO changed some things that had to be corrected ... and we see that the seats have been changed back to scheel mann seats. we see that it originally had glass and now it has perspex. we also see tinted glass, but didn't CSL come with clear glass on streetpack cars? we see that it previously had rear side markers and chrome bumpers and all of that has been shaved off. we see that it didn't have an air dam and now it does. Dan says they are all genuine parts ... he did not say original.
bottom line, an original 2275 streetpack car, originally inka and repainted inka ... in what looks to be very reasonable shape with a price tag of 160k. at that price, you have the headroom to fix / change anything and not be under water. you can either drive it as is or you can make it perfect. you could keep it or wait for the market to come back and make some money. i would probably dry ice the underside / strip the black off of the floor and get it correct. then i would enjoy it.
