As you and others mentioned, Hologram and Snack Bar hole are the biggies. Other things to check:
- Inlane damage where the ball drops onto the playfield from ramp, popper & bowl
- Have any mods been done? Lighted speaker panel, lighted bumpers, and the Swinks Snackbar are not essential but nice ones to have
- Broken plastics, particularly the car plastics on the left side. They should be fairly long, if not they have been broken off
- Wear at the Paid inserts above bumpers
- Make sure the lift ramp works or you will not get the ball to the whirlpool bowl
- Check the subway ramp under the playfield for damage (manual refers to it as "ball trough")
