Price evolution F13/F06

Hello, I’ve been trying to sell a 2017 F13 640d in the last three weeks. The car is very well there, with M package, original mileage, original paint, rear drive, accident-free, sapphire black, seats Cognac, 108k km. Overall, so not so bad starting criteria. Now the interest was very limited, although according to Mobile the price was considered very good and it was actually far too cheaply advertised. I know that winter is not the best season around sol I didn’t expect so few requests, but could it be that beautiful coupés in this price range (33k-38k) are no longer being asked?
