Vendo 125 where do i start?

Just found this website. I have a Vendo 125 machine in my Dad's barn.  We unplugged it about a year ago. At that time, it kept drinks ICE COLD.  However, the coin mechanism doesn't work well & many of the buttons  aren't working either. Nor are the lights.

I'd like to put it into service at my new water garden nursery. Is it worth cleaning up & where would I buy the coin mechanism? It says it takes one of the following mechanisms: 97AA24, 97AR24, 91E8301B, or 97E9303B.

Any advice for someone who has no knowledge of vending machines?

Thanks.....John
