Like it was mentioned, location matters.
In NYC, or any major city, you would get top dollar. Once out of metro areas it is much harder . If you have any full width dividers, I would mention that to possible buyers, also tell buyers, the casters would add >$100 if purchased separately .
Forget Ebay pricing, I think all Vidmar sellers on Ebay have been on drugs lately. In the last 9 months it seems the sellers are trying to raise the prices of the cabinets, but they forget, to inflate the price someone needs to buy them.
In NYC this would go for $600, would command better price with the original paint in good condition. Once you get in fairly rural areas the price drops, $300 is the absolute minimum I would go as a seller in a rural area; of course I would be dead, as I would not sell a Vidmar alive , so my estate would be selling it at 300. The safety detente missing is a minor detail, half of buyers would remove the mechanism anyway. Major deterrents would be damaged frame, major dent or rust ,everything else is minor
