I think it should reach $1500 - $1600. It has some serious moisture damage to the rear head panel, and that might scare off some buyers.
This is an example of an era that is in high demand. This title would fetch $1800 fully restored. Cab repainted and the head addressed - $2300-$2600.
Prices for SS games RESTORED are climbing. Demand is increasing, but collectors are becoming fussier - they want "bang for buck". This should be mandatory. Restore a game at a high level and buyers flock to your doorstep.
This title would be lucky to fetch $500, 10 years ago.
