Your name tells me you are biased. However, I'm going to answer you anyway.

Mercedes-Benz vehicles have had subpar quality for years. They break, maintenance is ridiculous and repairs are extremely overpriced. The resale value is terrible, the styling is generic, they are over-engineered and difficult to work on. 

Personally, I like them because when I see one pulling into the shop I know I'm about to get paid on that job. Would I own one? Never. 

the old ones were better because it was quality>status symbol like 240d 300d

now they cater to ppl who want to impress ppl they dont know with their tin cans lol.

the car you have... its a c class dude. atleast E class.
