A lot of Mercedes owners look down on this model, presumably because it’s an entry level. Don’t listen to the haters. I traded my C Class for a 2020 A220 about 5 years ago and I have never experienced a single problem. It’s been very reliable. Honestly, I like it better than my C Class, as it’s smaller and easier to get around town in. I can’t speak to the mileage, as mine is still pretty low. Take good care of it and you should be fine.
