Search car up to approx. 15,000€ (approx. 60,000km per year)

Hello, our old Passat gives up the spirit and now I am looking for a new economical car and am actually open to everything. I have a daily driving distance to work of 90km, so that I am at least 180km on the road on the day and in the year I come about 55000 – 60000 km. So far I had a Diesl, but also consider whether a gas car would be profitable. What would be feasible for the price and what would Sinvoll? Thanks already to everyone. Greeting Nacks
