I think restoration can probably go pretty far as long as there are no deep gouges.
I would offer: (a) let me try to get it professionally restored and if that doesn't work (b) I'll buy you a new wheel.
Personally, I think the offer to replace all 4 wheels is very generous but unnecessary. I think the "new shiny wheel" will wear quickly enough to match the general relative look of the others.
A few other options:
  • Get new wheel + get other 3 restored so they match better.
  • Buy a "excellent" condition used wheel, maybe it will match better with existing wheels.
