Compromise of comfort and performance sought…

Hello everyone! I am looking for a used car, to put it more precisely: – The car should be quiet in the interior, have an air conditioning and that was almost, “more needs” the car for me not to be able to at first sight I just moved from “Flachland” to “bergische Trier”, now the way to work is about 8km and 1-2 a month are 500-1000 motorway kilometers, hence the desire for a certain comfort. A small car is not for me. I prefer the limousine shape, which should not be filled with a V8, the car must not be undermotorized, but also not over-consumption, that means for me : clearly more than 10l are too much. VW Passat, div. BMW and Mercedes models are so with my favorites(from Trier from It’s just a stone’s throw to Luxembourg, so a bigger tank would be worth twice as much): The engine should not exceed the 2l engine displacement mark, looked around me at car cost check, which would cost me e.g. an e39 5 bmw (the e39 would be my favorite, but is flexible) and in the case of a passat, that goes already monthly, I hope from you a few well-meant suggestions and with VW I have not had any bad experiences yet, only white I still think that my father’s BMW was much quieter in the interior than my grandmother’s passat (both models from the end of the 80s). To the point: Which model with which engine of the mentioned manufacturer is particularly recommended in terms of reliability and maintenance costs or repair costs. Since this will be my first “self-purchased” car, I have already looked around and with regard to the monthly maintenance costs and fuel consumption. r me decided that the extra price for a more comfortable car than the typical small car is not the obstacle for me now, but you don’t have to exaggerate either, therefore the “compromise of comfort and performance”. Thanks already in advance for your suggestions
