I would worry about it...
The house I live in now, when I signed the deal, had a basketball
hoop on a steel pole embedded in concrete on the driveway. Although I
didn't care much, it was listed as "included" on the house contract.
When I took possession, the hoop was included, but it was beside the
house lying down.
It turns out that the complete bottom "ring" of the pole had rusted
clean away, and the pole had fallen in the wind. Not sure if it hit a
car or not, it it fell today it would hit my daily driver.
The rest of the pole is still PERFECTLY solid, I gave it to a friend
and he stuck it in the ground and used it again as a shorter pole for
younger kids. But you couldn't tell from looking at it that it had ever
rusted completely though.
The affected area was only a few mm thick, right along the bottom,
the rest was perfect. Would be very hard to detect in place.
