The sri lankans in japan also do this they agree with the seller and put a lower millage to the odo before geting the auction certificate,
we don't live in a dream world "defendertdi" imagines in japan
and there are many other ways that this can be done with a clear auction certificates,
so if u'r going for a recondition u should accept the fact that it could have done evan 150 000km in the 2 yrs it was used there,
because most cars i saw in japan had done more than 100 000km, but similar cars imported by sales here have only about 10 00km in their odo .
As in jap conditions the cars run about this much(100 000km), if they weren't met with an accident or kept for idiotic srilankan buyers to buy for more than it's brand new value,
The only way to be sure about the millage is to buy brand new or buy a 2nd hand one from a trustworthy source.
By the way cars do less millage in sri lanka so it will be more safe
