Commuter vehicle searched about 30000km/year

Hello, from January I will commute about 110km daily and therefore need a successor for my Polo TDI 6n2. The following would be important to me: – low costs (ideally optimum from tax/insurance/max. 5l consumption/replacement costs) – cruiser – safety (more crutch zone/airbags) I have read a few similar threads, there between LPG and diesel is considered and e.g. warned about the spare parts costs of the supposedly cheap Asians what I so like in Eri I find it difficult to estimate the total cost of ownership (incl. insurance/tax/replacement costs), i.e. whether, for example, a manufacturer A BJ 2003 is possibly cheaper in maintenance than a manufacturer B with only 3 years on the hump. Do you have a specific approach to how to look for your vehicle according to economic criteria (I don’t care about the brand)? Is there an overview of insurance and spare parts costs for the different models somewhere? Or does it make sense to Do you want to orientate yourself to the ADAC-minorist? What else does your thinking mean for the selection of a model? Thank you in advance! P.S.: Happy Festival!
