F56 Costs

Hello! Sorry that I’m opening another topic… with a planned car purchase you will have some questions. I’m thinking of buying an F56 or an A1 – for the mini I’ll ask here. It would probably become one from the end of 2015 with 102 hp. Do you have a rough idea of what this model could cost during the small and large inspection at each time? Does it matter if the car just has the HU and TÜV (??) behind it? Should you do the small and the big inspection of this car? Every 1 or 2 years? Are there any problems that this model has more often, which you should pay attention to? Or should you plan financially? How often do the brake discs have to be changed on average? I plan to drive about 15,000 km, but it could also be less. A mixture of rural road, city and motorway, but mainly the 150 km route between Stuttgart and Würzburg. I know that these are very many different questions. I am also grateful to you if you only know something to one sub-point!! Greetings, Pauline
