Mini Countryman Cooper S vs. Cooper SD // S All4 vs. SD All4

Hello guys, I want to buy myself a Mini Countryman Cooper S/SD/SAll4/SDAll4 (manual gearbox) in the near future. I need from the current Mini Countryman Cooper S/SD/SAll4/SDAll4 owners information about additional costs (consumption of city/motorway) and taxes…maybe even insurance ??? I guess I’ll come to my 15,000 – 20,000km a year. In addition, I would be grateful if you could tell me what extras you would give up in hindsight…welc he Extras is/are a MUST in the Mini Countryman !!! I hope you can help me with my request…I thank you already in advance.
