Review of my “high mileage” 2015 s550




















I actually purchased the car as is from the dealer, from the looks of it, it was maintained. The car was a demo car for Mercedes going dealer to dealer showing it off. When you pop the engine bay (I haven’t detailed it) it looks new in regards to hoses and belts. All I have done is a oil change today with LM 5w-40, ceratec and engine flush!

Dare I say that the W222 is one of the most reliable vehicles produced since 2015? Even lexus LS forum has plenty of complaints. Thoughts? Is this going to be true hassle-free 200K miles vehicle? Just like the 2001-2005 Lexus LS 430!!!?

My concern with these tunes is that why MBenz did not do it that way and why would a 3rd party have better knowledge about that car than MBenz. i.e.: does it have reliability consequences down the road!..

wondering about the tune, does it affect Rudd quality etc? When I had my mechanic do a PPI yesterday and change the oils etc he mentioned sometimes tuning these cars can cause issues. Does renntech comply with warranty still? I know these cars with a simple tune bring it close to
S63 AMG numbers.
