Mercedes C-Class years to avoid MERCEDES-BENZ C-Class Saloon (W205) (07.2013 - 02.2023)

There are some years of Mercedes C-Class that are really worth avoiding, in particular the 1994, 2001, 2013 and 2014 models, which had serious performance and reliability shortcomings compared to other years. When buying a C-Class, it is worth looking at later facelifted versions and choosing models with proven diesel engines, such as the OM646.
Years to consider:
Later facelifted models
(such as the W204 after the facelift) have proven themselves to be more reliable, especially with diesel engines.
Models with reliable diesel engines,
such as the OM646, are able to withstand high mileage without major repairs, which is a big plus for the buyer.
Why to avoid certain years:
1994:
Performance was far from ideal, making the model unreliable. 2001:
Also noted as a year with problematic characteristics that made it less attractive to buy.
2013 and 2014:
Made it into the not recommended list, which may be due to technical issues or insufficient development of the model during this period.
General recommendations:
Check reviews and reliability ratings for the specific generation and year, as quality can vary greatly.
Pay attention to the engine type, as some engines have proven to be more reliable than others.
Go for proven models, avoiding the earliest or problematic years.
