Purchase advice: Budget approx. 6000,-

Good evening together, after I had already been able to benefit a lot as a “member reader”, I now have a specific question that I would like to get rid of. I had a Mercedes S202 C180 from 1998 until recently. The car was a dream, except for Gevatter rust. Unfortunately, I had to reject the car due to massive rust problems, now something new has to be done. I have relatively clear ideas, which I try to formulate here: My driving profile: – approx. 10000-15000 km/a – next to trips to relatives and holiday trips daily work path about 20 km easy – I consider myself a relatively defensive driver, the C180 I moved with about 8L What is important to me: – Reliability (!!!): I like uncomplicated engines (e.g. non-charged 4-cylinder suction tube injector) and durable gears. The S202 C180 has been here for me the measure of things, except LMM nothing… – Control chain – Hand switch – A car, on which you can work yourself simple (e.g. brakeb eläge) can do without having to connect a PC – because I am “Larternparker” and the car is also moved in the winter in salt and snow, a galvanized body would be an advantage, after my S202 a little “rust damaged” – A nice interior. Again, the S202 is almost perfect in my eyes. – Since I often have to transport sports equipment, a not too small trunk would be important (or the possibility to fold the seats over), but does not necessarily have to a Combi be – green environmental badge What is not important to me: – from 0 to 100 in… – final speed, but 150 you should be able to drive already – consumption-optimized drive concepts (with 8L/100km I can live well) – electronic helpers, cornering light, etc. (ABS and possibly ESP completely enough) Optional: – All-wheel drive would be great, since I would like to ski more often with the car Financial: – 6000,- would be feel-good area, 7000,- absolute pain limit These are so in large measure me ine ideas, now I am very curious what suggestions/tips you have for me.
