That is indeed a very tidy late 280ZX been a while since I have seen one that tidy.
Like all Z’s these have appreciated quite well in the last few years, and in my opinion will continue to appreciate.
They are a nice car to drive, not as raw as a 240 or 260 but with a little work would make a great “GT” car, Air, Steer and lots of little luxuries.
