I bought my working, dedicated GNG 3 years ago for $300, needed cab work and one side was missing side art. I then bought a set of NOS side art for $50. I sold it this year for the $350 I had into it. I would say in today's economy, $2-300 would be fair if it was nice with no issues. If it's beat to shit, needs side art and a new CPO, I'd say $150. Fun game but hard as hell.
