Your game is definitely a restoration candidate, well worth the investment of time, effort and funds. It's a Solar City! The backglass and playfield look good to me. The coin door and cabinet will clean up just fine. I would keep the cabinet original and just touch it up. I'm not sure that rust remover and steel wool will sufficiently restore those legs. They might be severely pitted from the corrosion. I suppose that it's worth a try. However, I would probably just order a new set of legs, leg levelers and a new shooter rod plate from Pinball Resource and dedicate my time to the playfield, the cabinet and the electronics.

As an aside, a couple of years ago, a guy at Home Depot was selling solar energy panels for the Elon Musk company, Solar City. Naturally, I told the guy that his employer's company was named after a pinball machine.
