Economical, powerful, long-lasting car

Hello, I’ve already read a piece of it, but I don’t know how to make a decision. That’s why I wanted to ask you for forum help. I’m currently driving a Skoda Octavia 1,8Tsi. This one is great from the driving characteristics. The 160Ps are good enough to move forward quickly. The size is great, only the consumption and the fuel costs are too high. That’s why I had it converted to gas some time ago. After which I had some problems selling I am currently driving about 30000 – 35000 km a year and am now looking for something with similar performance. I already had a passat, Audi A4, and others with the 170hp diesel VW engines. However, I have read that the many problems have with cracked in the engine and other products…. So it went on to BMW E90. There are 163ps engine dolle Turbo problems and the 177hp engine, which has promised me the most so far, has problem with a grinding steering chain. Everything expensive and long when something happens. So what kind of car can I get without hesitation? Price should not cost more than 1200€. I thank you for your help and suggestions. Mfg
