Well, first, find a mod from any website and download it. Most mods come with exact instructions in the readme.txt file which detail the install. Be sure to back up your game as most save files are not compatible with mods, depending if you just modding cars, or if you modding the entire game. There are also programs which install mods for you, many to choose from, just go to a modding site and try one out.
