You can try offering $800, but be ready to be laughed at and shown the door. The boards alone are worth close to that. You are offering parts machine money for what sounds like a fairly typical route machine. If you are serious about the machine, I honestly think you should be offering at least $1500. Even that will be a stretch.

No offense, but I think you are expecting way too much value decrease due to it being a reimport and having a dirty playfield. If a little wear under the ramp is the only playfield issue, that's really not a big deal. That's very typical on this game. A banged up cab is par for the course on a route game. Hard to judge the extent without pics, but honestly I'm not hearing anything to make me believe this is only worth $800, much less double that.

So even with paying someone $1000 to fix it up, you are still expecting to only be $1800 into a fully shopped and at least semi-restored NGG? That is a nice goal, but completely unrealistic. Sorry. If you are expecting the cabinet to be all fixed up, playfield to be repaired, and fully shopped, you are talking about a ~$2500 machine, maybe more.

Best of luck!
