I know alot of Countryman owners have owned other Mini's before so I am wondering how they have held up to winter salt and rust? I am considering hitting the car with some Crown Rust Control before old man winter eats her up.

 

Haven't seen a rusty MINI yet; the newer ones have a 12-year rust perforation warranty.

 

You might want to consult with your MINI dealer before using any rust proofing products. Some have a tendency to trap water and cause rust, rather than prevent it. I would be concerned that might void your warranty regarding rust.
