I can see why your doing it, all I'm saying is that it may not be easy, and may not be best to keep talking about it here, if your going to take it further.
I'm pretty sure my kms have been wound back, since my log books state that my car was serviced at 122k odd kms in japan, when I bought the car it only had 94k or so k's, but I sought of thought that would be the case, and went into the purchase expecting that. Considering the engine was replaced and other work had been done, I thought it would even out.
