2002 Mercedes-Benz S430 Reviews

This model, like all MBs, are pieces of garbage. Also owned a C-Class. Continuous failures which include repeated failures: Airmatic, front end rebuilding issues, numerous electrical failures. These cars are poorly engineered, designed to be cost prohibitive. DO NOT BUY ONE OF THESE OR ANY MB PRODUCT. YOU WILL REGRET IT.

I have replaced the plastic that surrounds the bottom of the seats twice because they crack and the compartment under the seat for storage has no support, so it just hangs to the floor. I hear that's chronic. I have had problems with the front end and suspension. My rear window keeps letting down when I crank the car. My engine is ticking loud enough for you to wonder if I have oil or need it ...
