What are the main issues to look for on Who Dunnit?

Went to look at one today. A lot of black color scraped of the cabinet sides. A lot along the bottom of sides and a lot of nicks and scratches. I would say the cabinet is beat right now but some touch ups should go a long way. It didn't help that we scraped the crap out of the sides trying to get out of the basement.
All the ramps look good, one broken plastic, no play field wear spotted, 2 switch errors, 4 rusty legs and needs to be cleaned with new rubbers, coil sleeves, etc.
Never played the game so hope I like it. Thanks for the advice all!!!

There is a step motor with a tag that says good that I would pass along to a needed pinhead once I make sure my works fine. Any leads on plastics?

Just for my own curiosity what would you all pay for one in described condition. If I haven't included certain details of the machine just fill them in yourself.
