I don't not believe everything stated the ad but for $6000 the condition vs price of this one is about the best I've seen for a c30 around here. If I had the room I'd be tempted to go look at it.

This next c30 is definitely rougher but doesn't look too bad for $2300.

This GMC is pretty cool. The rear fenders were removed from the 8ft bed for the utility boxes but the bedsides are still there. Leave the utility boxes or get some fenders, your choice. Has typical north east rust but it's minimal especially for a $2500 driver
