Hi Bryan,

The number of owners shouldn’t affect its value too much – but its specification (M Sport? SE?), mileage and condition will be factors to consider when trying to value a 520d of this era. Mega-miles examples (more than 160,000km), as a rule, tend to be anything between €2,500 and €4,000. If it’s done less than that, or it’s a particularly high-spec, clean example. It could be worth more like €6,500-€7,500.
