Hello guys, my wife, my daughter & I want to get us a new car. It has to be a station wagon. We were in the Mercedes car dealership on Friday and are the C class(2012) & E class (2012) test cars. The E class has torn us from the stool. But for us still Audi A6(2011) & BMW 5’er (the new) would be in question. We have to finance the car. The car should hold for 8 years. I think there are no bad choices. First question: Would you go to a bank Then another question: I let myself be told that Mercedes has a lot of electrical problems. I haven’t found out about the others yet. ABer maybe you can tell me which problems are most common with the 3 AUtos. E Class: 220 CDI A6: 2.0 Diesel 5èr: 520d Many greetings
