What do you guys think about German cars about 20 years old.

Hellow! I'm looking to buy C200 or C180 Mercedes 2008 to 2013 model, Is there any specific or known fault in these cars? What other options do I have? If I want to buy something around the budget of 55 lac to 75 lac, I'm not a big fan of Local brands like Honda and Toyota. I need suggestions from the German Car owners?
