As much frustrating as it is, generalizing this practice would be bad for their business as they would lose a lot of traffic / sellers on the website.
However, i think this "verification" in their terms is known as "Pak wheels certified / inspected" cars .. i mean if one does not want be tricked by potential fraudulents and wants to have complete info. / knowledge about the said car, he/she should only hunt in the inspected cars segment.
I don't know, maybe other experts would have a solution to this ?!?
