Looking to buy my first BMW, a BMW 1 series 116i 2012. While inspecting the engine bay photo from seller, I can see exposed wires on the left side. Seller claims the car is not modified and that all work on it has been done by mechanics. Is this normal? Could not find this on any other photo of an F20. Should I be sceptical?
