Hello everyone, I'm new to the group and thanks for the welcome. I want some advice. I currently have a C200 supercharged 2001 with an m111 engine, but I want to get an E class, and I'm stuck between several cars. W211 2003. It's a 500 with an engine m113 , E350 diesel w212/w213 with om642 engine (2013-2018).Also what do you think about the new 6 cylinder inline m256 petrol , and om 656 diesel engines. Tell me which of the listed is the strongest and problem-free, such as engine, gearbox, quality - materials. Thanks in advance.I would be very grateful if you could explain me in detail please. I drive about 60 thousand kilometers a year. Which E class is the best choice in the long run, thank you.
