If the cirrhosis is advanced and more and more scar tissue forms in the liver, the damage is irreparable. The liver tissue is replaced by fibrous scar tissue as well as regenerative nodules (lumps that appear as a consequence of a process in which damaged tissue is regenerated).
Features like these help prolong the overall lifespan of the vehicle compared to older Mercedes models. Lifetime roadside assistance is offered with the C350. Otherwise, the warranty time frame for the Mercedes C350 is four years or 50,000 miles.
