Mercedes Benz

I read your article about buying a used mercedes. I have two options; c200 kompressor year 2005 kms 95,000. C180 year 2000 kms 70,000.

I like to know which model will be less troublesome in terms of engine and fuel efficiency and maintenance cost. I have a Toyota corolla 2010; I wonder if I am making a right decision in terms of realibility, ride and comfort.
