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.

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.
