Cars discussed that happen to be for sale by someone other than the person posting haven't generally been and shouldn't simply be deleted as a firm rule..
Don't we risk losing possible important pieces of the trail of cars that later prove genuine if we start doing this?.
My vote's always for trying to include important details, especially the Vin of cars that make short appearances here and try to always leave a clear trail we can find later..
Same goes for Vin stamped parts we come upon that have gone astray from their vehicles...the known digits or last six alone if that's all we have should be included when we can..
And when we do have these numbers at hand, we need to make sure to include them in a clear uncluttered format so later search results find them too...so posting a whole Vin or known digits needs to be clearly posted alone without the # sign or VIN stuck to the numbers..
