The list when I bought mine:
Head unit replaced & steering wheel control which wasn't working wired up.
Rubber gaiter round washer pipe to the boot was missing where someone had changed the pipe so that was replaced, fixing the leak into the boot.
Rear passenger door made water tight
At that point I only intended to keep it a few months but I just couldn't leave things broken. You're right though, most people just ignore little faults.
And of course several hours of clay bar, polish etc
