Commuter vehicle ~ 100km / day <15,000€

Hello all, I am currently looking for a reliable car for approx. 100km/day or 500km/week. The whole should be less than 15,000€ and at best not too expensive in maintenance / consumption. What I mean by reliable: In the past I had so far two cars: 2010 – 2019 a Honda Civic Bj. 2000 which I drove over 220,000km and had to give with approx. 340.000km due to too much rust in the press. During this time the oil was always so like tires, brakes, filters and spark plugs changed as well as at 260,000km times the timing belt (which still looked top). 2019 – today: a Clio III 1.2 currently approx. 265,000 km (was a gift at the mo. to the TüV). Anyway: – Driving profile: approx. 50km per direction [13km country road > 31km highway > 6km city] – approx. 25,000km/year – Budget: max. 15,000€ (do not have to be fully exhausted) – Gearbox: likes automatic – long-distance suitable -> Comfortable but also sporty (likes also ma l >200 km/h driving) – Combi (as child planned) – Not too expensive in maintenance On the subject of models and brands: I am very open. Currently I look more and more after the 2.0 TDIs of the VAG Group (Golf/Passat Variant; Leon ST; Skoda Octavia) – but the durability of the DSG transmission is questionable to me.
