If this isn't a scam, I am not sure how someone was able to title it as 5S214. The owner admits it is a K code clone, but I would think the current owner of 5S214 should contact Ebay and the seller. According to the registry, 5S214 was one of the cars that went to Peru. However, it doesn't look the the info has been updated recently. Just another reason why you should.
