How well does a BMW X3 hold its value? We bought a BMW F25 X3 xDrive 2.0d SE eight-speed automatic 21 months ago. The price including extras and a spare set of alloy wheels with winter tyres was £41,000. We recently asked our dealer to value the car when it was in for service (at 31,000 miles). He quoted £20,000. I understand depreciation is a big factor, but this seems a very low price for a quality car. We thought X3s held their value better than most. The simple answer is to keep the car. At a recent auction a 2012/61 BMW F25 X3 3.0 xDrive SE auto (10,000 miles) sold for £31,800, which was £1,000 above trade book at the time. Trade book for a 2011/11 X3 2.0dSE auto with 31,000 miles is £24,750, without all the extra kit. But it assumes that the car is not in any way damaged and has not transported smokers or dogs.
