It rusts because of the oxygen present in atmosphere. Rust is iron oxide - where the iron in the steel has combined with oxygen.

Preventing oxygen reaching the metal is the primary way to avoid rust, and this is done primarily with paints and other coatings.

To answer this question precisely would necessitate me knowing what you mean by the word "age". If car A is 10 years old with no rust, but car B is 10 years old with rust, they are both 10 years old. The age of both cars is 10 years. Only time itself causes age. However, if you ask the question "Can rust cause my car to become no longer useful?" The answer to this is - yes.
