2006 Mercedes-Benz S430 Reviews
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.
Its a great car!
