Mercedes-Benz S430 Reviews
This 11 year old car is as good as the day I purchased. I have owned about 40 vehicles and this is my number one in all categories.
I love my S430. I think the body styling as well as the sleek interior cannot be duplicated. It looks, both inside and out, more elegant than the new, more aggressive S series. It ages well, and with proper service and maintenance, it can be a dream to drive.
I have major suspension problems and the trunk looks open all the time.I have had to repair the suspention/ air shocks 3 times at $4,500 a whoop! There should have been a recall on the suspension system it is dangerous and costly. I have broken down 3 times with my car sitting on the street like a lower rider, SHAME ON MERCEDES BENZ
