I'm planning to buy an 2018+ X3 or X1 or any kind of beamer in China second hand so I was wondering if anyone knows what mileage I should aim below? Also are there any exploits to reset the odometer or accident history in the onboard computer system for any BMW cars that are built 2018 or above? Or if it does change, are there warnings (like in the bootloader) to look for? Does anyone know what in particular I should look for in a second hand car? Any help would be appreciated thanks a lot!
