Pinbot in 2025

Going to check out a Pinbot today that I might be purchasing— price seems really good— sub $2,000. I’ve got a list of things to check, but any suggestions other than these?

1- battery repositioning/corrosion on battery

2- if there’s mylar on the playfield (can’t really tell from pics), how does it look?

3- condition of the spiral ramp and if it’s original

4- run the self test and see if I can’t catch any lights/switches that might be malfunctioning

5- make sure the visor motor runs smoothly in one direction and doesn’t get caught up trying to move it down

I’ve never bought a System 11 game, and are trying to see if there are any other gremlins I should be looking out for? Thanks all!
