I've only just come across this thread, and I've not read all of the posts, so I don't know if it's been mentioned. I remembered this item, which was in the news a couple of years ago, and might be worth considering if anyone has this problem in the future. In this case the police used their resources to prove his guilt, and by the same token should be as fastidious in making sure a miscarriage of justice is not perpetrated. To even pursue a case, where there is reason to believe a car has been cloned, could be described as perverting the course of justice.
