leather seats look 'real' if you know what I mean, think most jdm's came with leather seats to be honest. The exhaust is deffo aftermarket, looks very like mine did when I got it. ZEES, only seem them on JDM cars, nice sound. He got carbon pilar and short shifter ... some nice mods there I'd say, would be nice to see engine bay. Wonder if that was a ICE setup made in Japan? Might still be Bose but not the headunit, try and find out the brand etc. Also ask if he imported it, if not who did he use and can he source the original auction report... pretty good if you can since they are pretty accurate.
