All Right, Greenberg and TM Productions Listings, Values, are all subject to the Eye of the Beholder. Its a way of figuring a price for resale or purchase. The Kelly Blue Book, NADA, Edmonds, and of course The Black Book are updated hourly, daily, and monthly....Cars are subject to Bank Approval, which is a story in itself. I like the Greenberg value as a starting place for pricing my trains on this forum. So far, its way off. I consider the offers, and make the adjusted pricing as close to the buyers wishes as I can. Postage is a problem on one item, one car, etc..... Its a fun hobby, Lets enjoy it together....
