Original equipment/condition: In classic cars, the more original, the better. This means seats, carpeting, gearshifts, pedals and other features should all be from the car's original manufacturer. Of course, the better the condition is of all these original components, the more valuable the car can be.

California. California has the most people of any state in the country, so it's no surprise that it also has the most classic car collectors.
