If you spend 5 minutes on the internet there are many complaints of the c class 2014-2018 in terms of reliability and its said up to 28 percent of those manufactured have significant faults. I'm looking at a 17 plate C200D 1.6 estate 31k on the clock and it does concern me. My goals are comfort , luxury, low tax, fuel efficiency and tech as far as my next car. Thoughts? Are they really as unreliable as is stated?
