Guys I just want to let you know if someone (who know how to do it the “right way”) decide to change mileage there will be NO way to check actual mileage no matter where you go, including the dealer. X5 keeps mileage record in 5 different places under protection, right guys can easily bypass protection and correct the mileage anyway they want. I used to know one guy in Russia who was doing that for living, I recall he said that changing mileage for X5, most BMWs and MBs is a piece of cake, with a few exceptions such as 2002+ 7-series and S-class but still possible. Sad but 95% of imported to Russia vehicles thru Latvia have corrected mileage. So impossible is nothing.
