I currently own a 2009 C300 4Matic Luxury 70k miles and am really considering the 2012-2014 facelift C300 4Matic sport. I love how the new interior looks and how it has a rear view camera/ many other things. I just wanted some insight if the facelift C300 are as reliable if not more than the prefacelift. Also if the new M276 engine is as reliable as the m272. Lastly if the facelift C300 have the same ESL and transfer case faults as the prefacelift. I have my eyes on a 2013 C300 4Matic sport. I just want some tips when looking at the car to make sure I don’t get stuck with a big repair bill down the road.
