Reliable car up to 7500 euros

Good day At the moment I am looking for a reliable car up to 7500 euros. It should be a saloon or SUV and thus 4/5 doorr. I absolutely want an automatic transmission and a good equipment and workmanship. So far I had the C class w203 and at the moment the w211 as avant-garde with absolute full equipment. Desto makes me not happy because I only have problems with it and the oh so great and reliable Mercedes only caused me problems with the G etriebe, Ölkühler, Kette, Elektronik etc etc… So I’m looking for something new, like other brands besides VW, Audi Skoda because I really hate VAG (please don’t take personally or all too seriously). I would like leather and automatic, that’s the most important thing. Brand doesn’t matter I’m Mercedes fan but was really disappointed until now. I thought of a w204 but it looks so pathetic from the inside. only plastic and everything cheap. the golf 5 from my colleague h at better equipment. Despite the reliability lies first. I want to have long what of the car and not get big problems (yes is certainly much required) . I can screw something myself and invest also gladly something . but if it should be like with the e class 3000 euro with a 6000 euro car then well … Please suggest me everything before I am very excited mfg
