Hi Conor,

Well, 2010 was the changeover period for the fifth-generation ‘E60’ 5 Series and the sixth-generation ‘F10’. So the first thing is: if it’s an E60 you’re looking at, it’ll be a grand or so cheaper than an equivalent mileage/spec F10. Realistically, 520ds are designed to do mega-miles on the motorway, so high mileages on them is not uncommon; therefore, you adding 40,000km to a car that has done 190,000km already won’t be a major problem for resale in the future, as many 2010 520d models have already done 230,000km and more anyway. We reckon the car you’re looking at should be around the €9,500 to €10,500 mark. Not sure what it will be worth in three years’ time – that will depend on the market and the effect a new 5 Series model would have on residuals of older generations.
