Mercedes-Benz S430 4MATIC Reviews

This car looks great yet has been a nightmare from day 1! wish I never bought it air suspension broke, radiator broke, cup holders are broken passenger vanity mirror broke, passenger mirror broke. This is luxury at its worst!
This is my second benz and it is an all around driving machine. On long or short trips it is super to drive. Only thing is the dealerships really charge a lot for maintenance.
This is the worst car ever I am actually on my way to the shop. Where can i dump it. Since i bought this junk it has been one problem after another. Please do not buy this car
