Can rust cause a car to age?

Rust is a common problem for cars, and it can indeed cause a car to age prematurely. Rust is the result of iron oxidation, which occurs when iron comes into contact with oxygen and moisture. This process is accelerated by exposure to salt, such as that found on roads in winter climates. Rust can cause the metal of the car to become weak and brittle, leading to structural problems and even failure. Additionally, rust can damage the car's paint job, making it look older than it is. To prevent rust, it is important to keep your car clean and dry, and to apply a rust-resistant coating to the metal.
