These tips have been developed to help you preserve and retain the value of your car. Unfortunately, there are people who have taken reproduction cars and tried to make them look like early originals. Due to the proliferation of reproductions over the past 30+ years, it is better to leave your car in original, as-raced condition. 

Try not to paint or restore your car.  This will mask the original features. It's hard to replace patina.

Resist cleaning or polishing.  This removes the patina which helps identify the car as an original.  If you have to clean it, just a mild cleaning is suggested.

Don't rest the car on it's tires. Tires will develop flat spots. It is best to rise the tires off the surface by resting the car on blocks or rotate tires 1/4 turn once a month.
