I can read 2 mileages on the export certificate, one is 55,000 dated 2014 and one is 35,400 dated 2013.
Where as the auction sheet says 31,000. An export certificate is made before the car is auction, A car maybe driven after its export certificate is made but once its auctioned its moved to the port and isnt driven. So somethings definitely fishy. Auction sheet mileage cannot be less then the export certificate mileage
PS: The sheet looks authentic too.
