Hi Caroline,

If it’s a 114d, 116d or 114i with 80,000km or more on it, in lowlier ES specification, it’s likely to be worth around €13,000 to €14,000. If it’s a 118d or 120d in M Sport guise and sub-100,000km, it could be worth €18,000 to €19,000. Your 2013 1 Series will fall somewhere in these price ranges – assuming it is in excellent condition with full history, of course.
