Car sales – no interested parties

Hello, I have now set my BMW for sale for the third time at Classifieds and Mobile. Like the last times, there are calls and also a few that have put the vehicle on their watch list, but not a single request. In the family we have sold 4 vehicles in this price range privately in the last 3 years and there have always been daily inquiries directly after hiring. The vehicle is unfortunately already from fourth hand (1st: until 2016 Leasing, 2nd: until 20 20 older lady, 3.: private holder, 4.: me). Since I have never had a vehicle with more than two previous owners in front of me, I now ask myself whether this could be the problem? In total, I invested in the BMW about 23,000 EUR purchase price still 5,000 EUR in repairs and the summer bikes with an annual drive of 45,000 km (had it for quite exactly one year). But now I drive at most 1x per week 20-30km with it to Berlin (the train is more pleasant with the whole construction work). For the short distances I don’t think the big diesel is done. What do you think is the reason for the missing requests and what would bother you, would you look for such a model?
