Yes multi coloured spray paint around all the prone rust areas is a concern on that blue 260z. So hard to tell from pictures if its had a quick bog job with paint or just been "touched up".
Looks pretty much original and only main areas of concern for me would ve the damage to rear qtr and maybe car has seen impact damage up front as drivers side front guard shows sign of impact and inspection covers not seem to close 100%.
Seems to have high interest so hopefully one of us can bring it home and keep it lol.
